Given numbers are 785,157,691,770

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

The LCM of 785,157,691,770 is 83534990.

Find LCM of 785,157,691,770 with Prime Factorization

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

5 x 157 x 1 x 1 x 691 x 154 = 83534990

Therefore, the lowest common multiple of 785,157,691,770 is 83534990.

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 157 x 691 x 770 = 65574967150

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

157 : 1, 157

691 : 1, 691

770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 785,157,691,770, is 1.

Now, the common factors can be found like this.

785:5x 157

157:157

691:691

770:2x 5x 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.

5x 157 = 785

Therefore, the value for common factors is 785.

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 = 65574967150/(1x785)

LCM = 65574967150/785

LCM = 83534990

Thus, we can understand that the LCM of 785,157,691,770 is 83534990.
