Given numbers are 639,961,341,77

The least common multiple of numbers can be find using the prime factorization method or LCM formula.

The LCM of 639,961,341,77 is 47284083.

Find LCM of 639,961,341,77 with Prime Factorization

Multiply the prime numbers at the bottom and the left side.

11 x 31 x 639 x 1 x 31 x 7 = 47284083

Therefore, the lowest common multiple of 639,961,341,77 is 47284083.

LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

Firstly, we have to find the product of all the numbers.

639 x 961 x 341 x 77 = 16123872303

Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.

639 : 1, 3, 9, 71, 213, 639

961 : 1, 31, 961

341 : 1, 11, 31, 341

77 : 1, 7, 11, 77

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 639,961,341,77, is 1.

Now, the common factors can be found like this.

639:3x 3x 71

961:31x 31

341:11x 31

77:7x 11

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

11x 31 = 341

Therefore, the value for common factors is 341.

Now that we have all the elements of the formula, we can plug them in to calculate the LCM.

LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

LCM = 16123872303/(1x341)

LCM = 16123872303/341

LCM = 47284083

Thus, we can understand that the LCM of 639,961,341,77 is 47284083.
