Given numbers are 577,642,131,770

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

The LCM of 577,642,131,770 is 18682838790.

Find LCM of 577,642,131,770 with Prime Factorization

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

2 x 577 x 321 x 131 x 385 = 18682838790

Therefore, the lowest common multiple of 577,642,131,770 is 18682838790.

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.

577 x 642 x 131 x 770 = 37365677580

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.

577 : 1, 577

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

131 : 1, 131

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 577,642,131,770, is 1.

Now, the common factors can be found like this.

577:577

642:2x 3x 107

131:131

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.

2 = 2

Therefore, the value for common factors is 2.

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 = 37365677580/(1x2)

LCM = 37365677580/2

LCM = 18682838790

Thus, we can understand that the LCM of 577,642,131,770 is 18682838790.
