Given numbers are 421,856,321,602

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

The LCM of 421,856,321,602 is 325419528.

Find LCM of 421,856,321,602 with Prime Factorization

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

2 x 107 x 421 x 4 x 3 x 301 = 325419528

Therefore, the lowest common multiple of 421,856,321,602 is 325419528.

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.

421 x 856 x 321 x 602 = 69639778992

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.

421 : 1, 421

856 : 1, 2, 4, 8, 107, 214, 428, 856

321 : 1, 3, 107, 321

602 : 1, 2, 7, 14, 43, 86, 301, 602

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 421,856,321,602, is 1.

Now, the common factors can be found like this.

421:421

856:2x 2x 2x 107

321:3x 107

602:2x 7x 43

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

2x 107 = 214

Therefore, the value for common factors is 214.

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 = 69639778992/(1x214)

LCM = 69639778992/214

LCM = 325419528

Thus, we can understand that the LCM of 421,856,321,602 is 325419528.
