Given numbers are 221,176,989,452

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

The LCM of 221,176,989,452 is 4346900272.

Find LCM of 221,176,989,452 with Prime Factorization

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

2 x 2 x 221 x 44 x 989 x 113 = 4346900272

Therefore, the lowest common multiple of 221,176,989,452 is 4346900272.

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.

221 x 176 x 989 x 452 = 17387601088

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.

221 : 1, 13, 17, 221

176 : 1, 2, 4, 8, 11, 16, 22, 44, 88, 176

989 : 1, 23, 43, 989

452 : 1, 2, 4, 113, 226, 452

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 221,176,989,452, is 1.

Now, the common factors can be found like this.

221:13x 17

176:2x 2x 2x 2x 11

989:23x 43

452:2x 2x 113

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 = 17387601088/(1x4)

LCM = 17387601088/4

LCM = 4346900272

Thus, we can understand that the LCM of 221,176,989,452 is 4346900272.
