Calculate the LCM of 310,676,451,786

Given numbers are 310,676,451,786

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

The LCM of 310,676,451,786 is 18571521540.

Find LCM of 310,676,451,786 with Prime Factorization


2 310, 676, 451, 786
155, 338, 451, 393

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

2 x 155 x 338 x 451 x 393 = 18571521540

Therefore, the lowest common multiple of 310,676,451,786 is 18571521540.

LCM Formula to Find Lowest Common Multiple of 310,676,451,786

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.

310 x 676 x 451 x 786 = 74286086160

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.

310 : 1, 2, 5, 10, 31, 62, 155, 310

676 : 1, 2, 4, 13, 26, 52, 169, 338, 676

451 : 1, 11, 41, 451

786 : 1, 2, 3, 6, 131, 262, 393, 786

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 310,676,451,786, is 1.

Now, the common factors can be found like this.

310:2x 5x 31

676:2x 2x 13x 13

451:11x 41

786:2x 3x 131

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 74286086160/(1x4)

LCM = 74286086160/4

LCM = 18571521540

Thus, we can understand that the LCM of 310,676,451,786 is 18571521540.
