Given numbers are 722,869,168,421

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

The LCM of 722,869,168,421 is 22188010152.

Find LCM of 722,869,168,421 with Prime Factorization

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

2 x 361 x 869 x 84 x 421 = 22188010152

Therefore, the lowest common multiple of 722,869,168,421 is 22188010152.

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.

722 x 869 x 168 x 421 = 44376020304

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.

722 : 1, 2, 19, 38, 361, 722

869 : 1, 11, 79, 869

168 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 21, 24, 28, 42, 56, 84, 168

421 : 1, 421

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 722,869,168,421, is 1.

Now, the common factors can be found like this.

722:2x 19x 19

869:11x 79

168:2x 2x 2x 3x 7

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.

2 = 2

Therefore, the value for common factors is 2.

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 = 44376020304/(1x2)

LCM = 44376020304/2

LCM = 22188010152

Thus, we can understand that the LCM of 722,869,168,421 is 22188010152.
