The LCM of 121,672,715,833 is 628948320.

Find LCM of 121,672,715,833 with Prime Factorization


7 121, 672, 715, 833
11 121, 96, 715, 119
11, 96, 65, 119

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

7 x 11 x 11 x 96 x 65 x 119 = 628948320

Therefore, the lowest common multiple of 121,672,715,833 is 628948320.

LCM Formula to Find Lowest Common Multiple of 121,672,715,833

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.

121 x 672 x 715 x 833 = 48429020640

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.

121 : 1, 11, 121

672 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 16, 21, 24, 28, 32, 42, 48, 56, 84, 96, 112, 168, 224, 336, 672

715 : 1, 5, 11, 13, 55, 65, 143, 715

833 : 1, 7, 17, 49, 119, 833

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 121,672,715,833, is 1.

Now, the common factors can be found like this.

121:11x 11

672:2x 2x 2x 2x 2x 3x 7

715:5x 11x 13

833:7x 7x 17

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

7x 11 = 77

Therefore, the value for common factors is 77.

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 = 48429020640/(1x77)

LCM = 48429020640/77

LCM = 628948320

Thus, we can understand that the LCM of 121,672,715,833 is 628948320.
