Given numbers are 571,695,139,642

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

The LCM of 571,695,139,642 is 254774490.

Find LCM of 571,695,139,642 with Prime Factorization

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

139 x 571 x 5 x 1 x 642 = 254774490

Therefore, the lowest common multiple of 571,695,139,642 is 254774490.

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.

571 x 695 x 139 x 642 = 35413654110

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.

571 : 1, 571

695 : 1, 5, 139, 695

139 : 1, 139

642 : 1, 2, 3, 6, 107, 214, 321, 642

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 571,695,139,642, is 1.

Now, the common factors can be found like this.

571:571

695:5x 139

139:139

642:2x 3x 107

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

139 = 139

Therefore, the value for common factors is 139.

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 = 35413654110/(1x139)

LCM = 35413654110/139

LCM = 254774490

Thus, we can understand that the LCM of 571,695,139,642 is 254774490.
