Given numbers are 147,639,121,284

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

The LCM of 147,639,121,284 is 15154524.

Find LCM of 147,639,121,284 with Prime Factorization

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

3 x 71 x 49 x 3 x 121 x 4 = 15154524

Therefore, the lowest common multiple of 147,639,121,284 is 15154524.

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.

147 x 639 x 121 x 284 = 3227913612

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.

147 : 1, 3, 7, 21, 49, 147

639 : 1, 3, 9, 71, 213, 639

121 : 1, 11, 121

284 : 1, 2, 4, 71, 142, 284

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 147,639,121,284, is 1.

Now, the common factors can be found like this.

147:3x 7x 7

639:3x 3x 71

121:11x 11

284:2x 2x 71

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

3x 71 = 213

Therefore, the value for common factors is 213.

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 = 3227913612/(1x213)

LCM = 3227913612/213

LCM = 15154524

Thus, we can understand that the LCM of 147,639,121,284 is 15154524.
