Given numbers are 641,172,946,658

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

The LCM of 641,172,946,658 is 399001988.

Find LCM of 641,172,946,658 with Prime Factorization

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

2 x 43 x 641 x 2 x 11 x 329 = 399001988

Therefore, the lowest common multiple of 641,172,946,658 is 399001988.

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.

641 x 172 x 946 x 658 = 68628341936

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.

641 : 1, 641

172 : 1, 2, 4, 43, 86, 172

946 : 1, 2, 11, 22, 43, 86, 473, 946

658 : 1, 2, 7, 14, 47, 94, 329, 658

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 641,172,946,658, is 1.

Now, the common factors can be found like this.

641:641

172:2x 2x 43

946:2x 11x 43

658:2x 7x 47

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 43 = 172

Therefore, the value for common factors is 172.

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 = 68628341936/(1x172)

LCM = 68628341936/172

LCM = 399001988

Thus, we can understand that the LCM of 641,172,946,658 is 399001988.
