Calculate the LCM of 787,706,692,521,630

Given numbers are 787,706,692,521,630

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

The LCM of 787,706,692,521,630 is 31550322967380.

Find LCM of 787,706,692,521,630 with Prime Factorization


2 787, 706, 692, 521, 630
787, 353, 346, 521, 315

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

2 x 787 x 353 x 346 x 521 x 315 = 31550322967380

Therefore, the lowest common multiple of 787,706,692,521,630 is 31550322967380.

LCM Formula to Find Lowest Common Multiple of 787,706,692,521,630

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.

787 x 706 x 692 x 521 x 630 = 126201291869520

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.

787 : 1, 787

706 : 1, 2, 353, 706

692 : 1, 2, 4, 173, 346, 692

521 : 1, 521

630 : 1, 2, 3, 5, 6, 7, 9, 10, 14, 15, 18, 21, 30, 35, 42, 45, 63, 70, 90, 105, 126, 210, 315, 630

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 787,706,692,521,630, is 1.

Now, the common factors can be found like this.

787:787

706:2x 353

692:2x 2x 173

521:521

630:2x 3x 3x 5x 7

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 = 126201291869520/(1x4)

LCM = 126201291869520/4

LCM = 31550322967380

Thus, we can understand that the LCM of 787,706,692,521,630 is 31550322967380.
