Given numbers are 785,487,757,686,620

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

The LCM of 785,487,757,686,620 is 12308646601580.

Find LCM of 785,487,757,686,620 with Prime Factorization

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

2 x 5 x 157 x 487 x 757 x 343 x 62 = 12308646601580

Therefore, the lowest common multiple of 785,487,757,686,620 is 12308646601580.

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.

785 x 487 x 757 x 686 x 620 = 123086466015800

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.

785 : 1, 5, 157, 785

487 : 1, 487

757 : 1, 757

686 : 1, 2, 7, 14, 49, 98, 343, 686

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 785,487,757,686,620, is 1.

Now, the common factors can be found like this.

785:5x 157

487:487

757:757

686:2x 7x 7x 7

620:2x 2x 5x 31

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

2x 5 = 10

Therefore, the value for common factors is 10.

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 = 123086466015800/(1x10)

LCM = 123086466015800/10

LCM = 12308646601580

Thus, we can understand that the LCM of 785,487,757,686,620 is 12308646601580.
