Given numbers are 631,163,290,988,140

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

The LCM of 631,163,290,988,140 is 103143045460.

Find LCM of 631,163,290,988,140 with Prime Factorization

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

2 x 2 x 5 x 631 x 163 x 29 x 247 x 7 = 103143045460

Therefore, the lowest common multiple of 631,163,290,988,140 is 103143045460.

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.

631 x 163 x 290 x 988 x 140 = 4125721818400

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.

631 : 1, 631

163 : 1, 163

290 : 1, 2, 5, 10, 29, 58, 145, 290

988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988

140 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 70, 140

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 631,163,290,988,140, is 1.

Now, the common factors can be found like this.

631:631

163:163

290:2x 5x 29

988:2x 2x 13x 19

140:2x 2x 5x 7

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

2x 2x 2x 5 = 40

Therefore, the value for common factors is 40.

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 = 4125721818400/(1x40)

LCM = 4125721818400/40

LCM = 103143045460

Thus, we can understand that the LCM of 631,163,290,988,140 is 103143045460.
