Calculate the LCM of 688,913,278,802

Given numbers are 688,913,278,802

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

The LCM of 688,913,278,802 is 35012118416.

Find LCM of 688,913,278,802 with Prime Factorization


2 688, 913, 278, 802
344, 913, 139, 401

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

2 x 344 x 913 x 139 x 401 = 35012118416

Therefore, the lowest common multiple of 688,913,278,802 is 35012118416.

LCM Formula to Find Lowest Common Multiple of 688,913,278,802

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.

688 x 913 x 278 x 802 = 140048473664

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.

688 : 1, 2, 4, 8, 16, 43, 86, 172, 344, 688

913 : 1, 11, 83, 913

278 : 1, 2, 139, 278

802 : 1, 2, 401, 802

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 688,913,278,802, is 1.

Now, the common factors can be found like this.

688:2x 2x 2x 2x 43

913:11x 83

278:2x 139

802:2x 401

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 = 140048473664/(1x4)

LCM = 140048473664/4

LCM = 35012118416

Thus, we can understand that the LCM of 688,913,278,802 is 35012118416.
