Given numbers are 671,747,321,154,654

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

The LCM of 671,747,321,154,654 is 81842979834.

Find LCM of 671,747,321,154,654 with Prime Factorization

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

2 x 3 x 11 x 61 x 249 x 107 x 7 x 109 = 81842979834

Therefore, the lowest common multiple of 671,747,321,154,654 is 81842979834.

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.

671 x 747 x 321 x 154 x 654 = 16204910007132

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.

671 : 1, 11, 61, 671

747 : 1, 3, 9, 83, 249, 747

321 : 1, 3, 107, 321

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

654 : 1, 2, 3, 6, 109, 218, 327, 654

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 671,747,321,154,654, is 1.

Now, the common factors can be found like this.

671:11x 61

747:3x 3x 83

321:3x 107

154:2x 7x 11

654:2x 3x 109

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

2x 3x 3x 11 = 198

Therefore, the value for common factors is 198.

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 = 16204910007132/(1x198)

LCM = 16204910007132/198

LCM = 81842979834

Thus, we can understand that the LCM of 671,747,321,154,654 is 81842979834.
