Calculate the LCM of 972,882,617,981

Given numbers are 972,882,617,981

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

The LCM of 972,882,617,981 is 3203125884.

Find LCM of 972,882,617,981 with Prime Factorization


2 972, 882, 617, 981
3 486, 441, 617, 981
3 162, 147, 617, 327
54, 49, 617, 109

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

2 x 3 x 3 x 54 x 49 x 617 x 109 = 3203125884

Therefore, the lowest common multiple of 972,882,617,981 is 3203125884.

LCM Formula to Find Lowest Common Multiple of 972,882,617,981

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.

972 x 882 x 617 x 981 = 518906393208

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.

972 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 81, 108, 162, 243, 324, 486, 972

882 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 42, 49, 63, 98, 126, 147, 294, 441, 882

617 : 1, 617

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 972,882,617,981, is 1.

Now, the common factors can be found like this.

972:2x 2x 3x 3x 3x 3x 3

882:2x 3x 3x 7x 7

617:617

981:3x 3x 109

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 3x 3 = 162

Therefore, the value for common factors is 162.

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 = 518906393208/(1x162)

LCM = 518906393208/162

LCM = 3203125884

Thus, we can understand that the LCM of 972,882,617,981 is 3203125884.
