Given numbers are 620,138,402,991,107

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

The LCM of 620,138,402,991,107 is 303929611620.

Find LCM of 620,138,402,991,107 with Prime Factorization

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

2 x 3 x 310 x 23 x 67 x 991 x 107 = 303929611620

Therefore, the lowest common multiple of 620,138,402,991,107 is 303929611620.

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.

620 x 138 x 402 x 991 x 107 = 3647155339440

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.

620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620

138 : 1, 2, 3, 6, 23, 46, 69, 138

402 : 1, 2, 3, 6, 67, 134, 201, 402

991 : 1, 991

107 : 1, 107

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 620,138,402,991,107, is 1.

Now, the common factors can be found like this.

620:2x 2x 5x 31

138:2x 3x 23

402:2x 3x 67

991:991

107:107

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

2x 2x 3 = 12

Therefore, the value for common factors is 12.

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 = 3647155339440/(1x12)

LCM = 3647155339440/12

LCM = 303929611620

Thus, we can understand that the LCM of 620,138,402,991,107 is 303929611620.
