Given numbers are 419,294,220,128,323

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

The LCM of 419,294,220,128,323 is 140057554560.

Find LCM of 419,294,220,128,323 with Prime Factorization

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

2 x 2 x 419 x 147 x 55 x 32 x 323 = 140057554560

Therefore, the lowest common multiple of 419,294,220,128,323 is 140057554560.

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.

419 x 294 x 220 x 128 x 323 = 1120460436480

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.

419 : 1, 419

294 : 1, 2, 3, 6, 7, 14, 21, 42, 49, 98, 147, 294

220 : 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220

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

323 : 1, 17, 19, 323

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 419,294,220,128,323, is 1.

Now, the common factors can be found like this.

419:419

294:2x 3x 7x 7

220:2x 2x 5x 11

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

323:17x 19

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 2 = 8

Therefore, the value for common factors is 8.

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 = 1120460436480/(1x8)

LCM = 1120460436480/8

LCM = 140057554560

Thus, we can understand that the LCM of 419,294,220,128,323 is 140057554560.
