Calculate the LCM of 149,618,780,315

Given numbers are 149,618,780,315

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

The LCM of 149,618,780,315 is 251383860.

Find LCM of 149,618,780,315 with Prime Factorization


2 149, 618, 780, 315
3 149, 309, 390, 315
5 149, 103, 130, 105
149, 103, 26, 21

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

2 x 3 x 5 x 149 x 103 x 26 x 21 = 251383860

Therefore, the lowest common multiple of 149,618,780,315 is 251383860.

LCM Formula to Find Lowest Common Multiple of 149,618,780,315

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.

149 x 618 x 780 x 315 = 22624547400

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.

149 : 1, 149

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

780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780

315 : 1, 3, 5, 7, 9, 15, 21, 35, 45, 63, 105, 315

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 149,618,780,315, is 1.

Now, the common factors can be found like this.

149:149

618:2x 3x 103

780:2x 2x 3x 5x 13

315:3x 3x 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 3x 3x 5 = 90

Therefore, the value for common factors is 90.

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 = 22624547400/(1x90)

LCM = 22624547400/90

LCM = 251383860

Thus, we can understand that the LCM of 149,618,780,315 is 251383860.
