Calculate the LCM of 865,780,551,536,355

Given numbers are 865,780,551,536,355

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

The LCM of 865,780,551,536,355 is 707384357160.

Find LCM of 865,780,551,536,355 with Prime Factorization


2 865, 780, 551, 536, 355
2 865, 390, 551, 268, 355
5 865, 195, 551, 134, 355
173, 39, 551, 134, 71

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

2 x 2 x 5 x 173 x 39 x 551 x 134 x 71 = 707384357160

Therefore, the lowest common multiple of 865,780,551,536,355 is 707384357160.

LCM Formula to Find Lowest Common Multiple of 865,780,551,536,355

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.

865 x 780 x 551 x 536 x 355 = 70738435716000

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.

865 : 1, 5, 173, 865

780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780

551 : 1, 19, 29, 551

536 : 1, 2, 4, 8, 67, 134, 268, 536

355 : 1, 5, 71, 355

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 865,780,551,536,355, is 1.

Now, the common factors can be found like this.

865:5x 173

780:2x 2x 3x 5x 13

551:19x 29

536:2x 2x 2x 67

355:5x 71

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

2x 2x 5x 5 = 100

Therefore, the value for common factors is 100.

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 = 70738435716000/(1x100)

LCM = 70738435716000/100

LCM = 707384357160

Thus, we can understand that the LCM of 865,780,551,536,355 is 707384357160.
