Calculate the LCM of 618,651,788,910

Given numbers are 618,651,788,910

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

The LCM of 618,651,788,910 is 3434454660.

Find LCM of 618,651,788,910 with Prime Factorization


2 618, 651, 788, 910
3 309, 651, 394, 455
7 103, 217, 394, 455
103, 31, 394, 65

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

2 x 3 x 7 x 103 x 31 x 394 x 65 = 3434454660

Therefore, the lowest common multiple of 618,651,788,910 is 3434454660.

LCM Formula to Find Lowest Common Multiple of 618,651,788,910

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.

618 x 651 x 788 x 910 = 288494191440

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.

618 : 1, 2, 3, 6, 103, 206, 309, 618

651 : 1, 3, 7, 21, 31, 93, 217, 651

788 : 1, 2, 4, 197, 394, 788

910 : 1, 2, 5, 7, 10, 13, 14, 26, 35, 65, 70, 91, 130, 182, 455, 910

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 618,651,788,910, is 1.

Now, the common factors can be found like this.

618:2x 3x 103

651:3x 7x 31

788:2x 2x 197

910:2x 5x 7x 13

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 3x 7 = 84

Therefore, the value for common factors is 84.

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 = 288494191440/(1x84)

LCM = 288494191440/84

LCM = 3434454660

Thus, we can understand that the LCM of 618,651,788,910 is 3434454660.
