Given numbers are 669,431,517,430,892

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

The LCM of 669,431,517,430,892 is 128201286180.

Find LCM of 669,431,517,430,892 with Prime Factorization

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

2 x 223 x 3 x 431 x 517 x 215 x 2 = 128201286180

Therefore, the lowest common multiple of 669,431,517,430,892 is 128201286180.

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.

669 x 431 x 517 x 430 x 892 = 57177773636280

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.

669 : 1, 3, 223, 669

431 : 1, 431

517 : 1, 11, 47, 517

430 : 1, 2, 5, 10, 43, 86, 215, 430

892 : 1, 2, 4, 223, 446, 892

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 669,431,517,430,892, is 1.

Now, the common factors can be found like this.

669:3x 223

431:431

517:11x 47

430:2x 5x 43

892:2x 2x 223

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

2x 223 = 446

Therefore, the value for common factors is 446.

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 = 57177773636280/(1x446)

LCM = 57177773636280/446

LCM = 128201286180

Thus, we can understand that the LCM of 669,431,517,430,892 is 128201286180.
