Given numbers are 354,956,456,545,421

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

The LCM of 354,956,456,545,421 is 1475344198920.

Find LCM of 354,956,456,545,421 with Prime Factorization

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

2 x 2 x 3 x 59 x 239 x 38 x 545 x 421 = 1475344198920

Therefore, the lowest common multiple of 354,956,456,545,421 is 1475344198920.

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.

354 x 956 x 456 x 545 x 421 = 35408260774080

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.

354 : 1, 2, 3, 6, 59, 118, 177, 354

956 : 1, 2, 4, 239, 478, 956

456 : 1, 2, 3, 4, 6, 8, 12, 19, 24, 38, 57, 76, 114, 152, 228, 456

545 : 1, 5, 109, 545

421 : 1, 421

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 354,956,456,545,421, is 1.

Now, the common factors can be found like this.

354:2x 3x 59

956:2x 2x 239

456:2x 2x 2x 3x 19

545:5x 109

421:421

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 3 = 24

Therefore, the value for common factors is 24.

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 = 35408260774080/(1x24)

LCM = 35408260774080/24

LCM = 1475344198920

Thus, we can understand that the LCM of 354,956,456,545,421 is 1475344198920.
