Given numbers are 630,784,127,421

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

The LCM of 630,784,127,421 is 1886315760.

Find LCM of 630,784,127,421 with Prime Factorization

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

2 x 7 x 45 x 56 x 127 x 421 = 1886315760

Therefore, the lowest common multiple of 630,784,127,421 is 1886315760.

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.

630 x 784 x 127 x 421 = 26408420640

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.

630 : 1, 2, 3, 5, 6, 7, 9, 10, 14, 15, 18, 21, 30, 35, 42, 45, 63, 70, 90, 105, 126, 210, 315, 630

784 : 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 392, 784

127 : 1, 127

421 : 1, 421

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 630,784,127,421, is 1.

Now, the common factors can be found like this.

630:2x 3x 3x 5x 7

784:2x 2x 2x 2x 7x 7

127:127

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.

2x 7 = 14

Therefore, the value for common factors is 14.

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 = 26408420640/(1x14)

LCM = 26408420640/14

LCM = 1886315760

Thus, we can understand that the LCM of 630,784,127,421 is 1886315760.
