The LCM of 648,701,979,742 is 164986961832.

Find LCM of 648,701,979,742 with Prime Factorization


2 648, 701, 979, 742
324, 701, 979, 371

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

2 x 324 x 701 x 979 x 371 = 164986961832

Therefore, the lowest common multiple of 648,701,979,742 is 164986961832.

LCM Formula to Find Lowest Common Multiple of 648,701,979,742

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.

648 x 701 x 979 x 742 = 329973923664

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.

648 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 81, 108, 162, 216, 324, 648

701 : 1, 701

979 : 1, 11, 89, 979

742 : 1, 2, 7, 14, 53, 106, 371, 742

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 648,701,979,742, is 1.

Now, the common factors can be found like this.

648:2x 2x 2x 3x 3x 3x 3

701:701

979:11x 89

742:2x 7x 53

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

2 = 2

Therefore, the value for common factors is 2.

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 = 329973923664/(1x2)

LCM = 329973923664/2

LCM = 164986961832

Thus, we can understand that the LCM of 648,701,979,742 is 164986961832.
