Calculate the LCM of 981,642,564,133

Given numbers are 981,642,564,133

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

The LCM of 981,642,564,133 is 2624594868.

Find LCM of 981,642,564,133 with Prime Factorization


2 981, 642, 564, 133
3 981, 321, 282, 133
327, 107, 94, 133

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

2 x 3 x 327 x 107 x 94 x 133 = 2624594868

Therefore, the lowest common multiple of 981,642,564,133 is 2624594868.

LCM Formula to Find Lowest Common Multiple of 981,642,564,133

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.

981 x 642 x 564 x 133 = 47242707624

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.

981 : 1, 3, 9, 109, 327, 981

642 : 1, 2, 3, 6, 107, 214, 321, 642

564 : 1, 2, 3, 4, 6, 12, 47, 94, 141, 188, 282, 564

133 : 1, 7, 19, 133

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 981,642,564,133, is 1.

Now, the common factors can be found like this.

981:3x 3x 109

642:2x 3x 107

564:2x 2x 3x 47

133:7x 19

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 3 = 18

Therefore, the value for common factors is 18.

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 = 47242707624/(1x18)

LCM = 47242707624/18

LCM = 2624594868

Thus, we can understand that the LCM of 981,642,564,133 is 2624594868.
