Given numbers are 989,421,220,724

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

The LCM of 989,421,220,724 is 16579813580.

Find LCM of 989,421,220,724 with Prime Factorization

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

2 x 2 x 989 x 421 x 55 x 181 = 16579813580

Therefore, the lowest common multiple of 989,421,220,724 is 16579813580.

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.

989 x 421 x 220 x 724 = 66319254320

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.

989 : 1, 23, 43, 989

421 : 1, 421

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

724 : 1, 2, 4, 181, 362, 724

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 989,421,220,724, is 1.

Now, the common factors can be found like this.

989:23x 43

421:421

220:2x 2x 5x 11

724:2x 2x 181

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 66319254320/(1x4)

LCM = 66319254320/4

LCM = 16579813580

Thus, we can understand that the LCM of 989,421,220,724 is 16579813580.
