Given numbers are 860,717,718,128,154

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

The LCM of 860,717,718,128,154 is 545447253120.

Find LCM of 860,717,718,128,154 with Prime Factorization

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

2 x 2 x 215 x 717 x 359 x 32 x 77 = 545447253120

Therefore, the lowest common multiple of 860,717,718,128,154 is 545447253120.

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.

860 x 717 x 718 x 128 x 154 = 8727156049920

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.

860 : 1, 2, 4, 5, 10, 20, 43, 86, 172, 215, 430, 860

717 : 1, 3, 239, 717

718 : 1, 2, 359, 718

128 : 1, 2, 4, 8, 16, 32, 64, 128

154 : 1, 2, 7, 11, 14, 22, 77, 154

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 860,717,718,128,154, is 1.

Now, the common factors can be found like this.

860:2x 2x 5x 43

717:3x 239

718:2x 359

128:2x 2x 2x 2x 2x 2x 2

154:2x 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.

2x 2x 2x 2 = 16

Therefore, the value for common factors is 16.

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 = 8727156049920/(1x16)

LCM = 8727156049920/16

LCM = 545447253120

Thus, we can understand that the LCM of 860,717,718,128,154 is 545447253120.
