Calculate the LCM of 151,855,421,504

Given numbers are 151,855,421,504

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

The LCM of 151,855,421,504 is 3043779480.

Find LCM of 151,855,421,504 with Prime Factorization


3 151, 855, 421, 504
3 151, 285, 421, 168
151, 95, 421, 56

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

3 x 3 x 151 x 95 x 421 x 56 = 3043779480

Therefore, the lowest common multiple of 151,855,421,504 is 3043779480.

LCM Formula to Find Lowest Common Multiple of 151,855,421,504

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.

151 x 855 x 421 x 504 = 27394015320

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.

151 : 1, 151

855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855

421 : 1, 421

504 : 1, 2, 3, 4, 6, 7, 8, 9, 12, 14, 18, 21, 24, 28, 36, 42, 56, 63, 72, 84, 126, 168, 252, 504

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 151,855,421,504, is 1.

Now, the common factors can be found like this.

151:151

855:3x 3x 5x 19

421:421

504:2x 2x 2x 3x 3x 7

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

3x 3 = 9

Therefore, the value for common factors is 9.

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 = 27394015320/(1x9)

LCM = 27394015320/9

LCM = 3043779480

Thus, we can understand that the LCM of 151,855,421,504 is 3043779480.
