Given numbers are 403,971,117,988

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

The LCM of 403,971,117,988 is 267658092.

Find LCM of 403,971,117,988 with Prime Factorization

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

13 x 31 x 971 x 9 x 76 = 267658092

Therefore, the lowest common multiple of 403,971,117,988 is 267658092.

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.

403 x 971 x 117 x 988 = 45234217548

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.

403 : 1, 13, 31, 403

971 : 1, 971

117 : 1, 3, 9, 13, 39, 117

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 403,971,117,988, is 1.

Now, the common factors can be found like this.

403:13x 31

971:971

117:3x 3x 13

988:2x 2x 13x 19

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

13x 13 = 169

Therefore, the value for common factors is 169.

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 = 45234217548/(1x169)

LCM = 45234217548/169

LCM = 267658092

Thus, we can understand that the LCM of 403,971,117,988 is 267658092.
