Find LCM of 657,629,561,678,758 with Prime Factorization


2 657, 629, 561, 678, 758
3 657, 629, 561, 339, 379
17 219, 629, 187, 113, 379
219, 37, 11, 113, 379

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

2 x 3 x 17 x 219 x 37 x 11 x 113 x 379 = 389364497082

Therefore, the lowest common multiple of 657,629,561,678,758 is 389364497082.

LCM Formula to Find Lowest Common Multiple of 657,629,561,678,758

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.

657 x 629 x 561 x 678 x 758 = 119145536107092

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.

657 : 1, 3, 9, 73, 219, 657

629 : 1, 17, 37, 629

561 : 1, 3, 11, 17, 33, 51, 187, 561

678 : 1, 2, 3, 6, 113, 226, 339, 678

758 : 1, 2, 379, 758

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 657,629,561,678,758, is 1.

Now, the common factors can be found like this.

657:3x 3x 73

629:17x 37

561:3x 11x 17

678:2x 3x 113

758:2x 379

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 17 = 306

Therefore, the value for common factors is 306.

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 = 119145536107092/(1x306)

LCM = 119145536107092/306

LCM = 389364497082

Thus, we can understand that the LCM of 657,629,561,678,758 is 389364497082.
