दोन संख्यांचा लसावी व मसावी अनुक्रमे 432 व 72 आहे. दोन संख्यांपैकी एक संख्या 216 असेल, तर दुसरी संख्या काढा. The LCM of two numbers is 432 and their HCF is 36.

The HCF of 30 and 42 is 6. To calculate the HCF of 30 and 42, we need to factor each number (factors of 30 = 1, 2, 3, 5, 6, 10, 15, 30; factors of 42 = 1, 2, 3, 6, 7, 14, 21, 42) and choose the highest factor that exactly divides both 30 and 42, i.e. 6.

The highest common factor (HCF) is found by finding all common factors of two numbers and selecting the largest one. For example, 8 and 12 have common factors of 1, 2 and 4. The highest common factor is 4.

In the method of prime factorization, we write the given numbers as the product of their prime factors. Now, the L.C.M will be the product of multiplying the highest power of each prime number together. Hence, the L.C.M of 36, 60 and 72 is 360.

The highest number that divides 12, 36, and 48 exactly is their highest common factor. The HCF of 12, 36, and 48 is 12. ∴ The highest number that divides 12, 36, and 48 is 12.

LCM of 36 and 72 is 72. The common multiple divisible evenly by the numbers 36 and 72 is the LCM. Students can learn to get the least common multiples of 36 and 72 from the common multiples. (36, 72, 108, 144, 180, 216, 252, ….)

LCM is the smallest number exactly divisible by 72 and 120. Multiples of 72 = 72, 144, 216, 288, 360, …. Multiples of 120 = 120, 240, 360, 480, 600, ….. Hence, the LCM of 72 and 120 is 360.
