Calculate the LCM of 614,921,138,852

Given numbers are 614,921,138,852

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

The LCM of 614,921,138,852 is 6015972.

Find LCM of 614,921,138,852 with Prime Factorization


2 614, 921, 138, 852
3 307, 921, 69, 426
307 307, 307, 23, 142
1, 1, 23, 142

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

2 x 3 x 307 x 1 x 1 x 23 x 142 = 6015972

Therefore, the lowest common multiple of 614,921,138,852 is 6015972.

LCM Formula to Find Lowest Common Multiple of 614,921,138,852

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.

614 x 921 x 138 x 852 = 66488522544

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.

614 : 1, 2, 307, 614

921 : 1, 3, 307, 921

138 : 1, 2, 3, 6, 23, 46, 69, 138

852 : 1, 2, 3, 4, 6, 12, 71, 142, 213, 284, 426, 852

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 614,921,138,852, is 1.

Now, the common factors can be found like this.

614:2x 307

921:3x 307

138:2x 3x 23

852:2x 2x 3x 71

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 3x 307 = 11052

Therefore, the value for common factors is 11052.

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 = 66488522544/(1x11052)

LCM = 66488522544/11052

LCM = 6015972

Thus, we can understand that the LCM of 614,921,138,852 is 6015972.
