Calculate the LCM of 726,638,683,971

Given numbers are 726,638,683,971

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

The LCM of 726,638,683,971 is 13962865422.

Find LCM of 726,638,683,971 with Prime Factorization


2 726, 638, 683, 971
11 363, 319, 683, 971
33, 29, 683, 971

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

2 x 11 x 33 x 29 x 683 x 971 = 13962865422

Therefore, the lowest common multiple of 726,638,683,971 is 13962865422.

LCM Formula to Find Lowest Common Multiple of 726,638,683,971

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.

726 x 638 x 683 x 971 = 307183039284

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.

726 : 1, 2, 3, 6, 11, 22, 33, 66, 121, 242, 363, 726

638 : 1, 2, 11, 22, 29, 58, 319, 638

683 : 1, 683

971 : 1, 971

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 726,638,683,971, is 1.

Now, the common factors can be found like this.

726:2x 3x 11x 11

638:2x 11x 29

683:683

971:971

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

2x 11 = 22

Therefore, the value for common factors is 22.

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 = 307183039284/(1x22)

LCM = 307183039284/22

LCM = 13962865422

Thus, we can understand that the LCM of 726,638,683,971 is 13962865422.
