Calculate the LCM of 688,632,641,292

Given numbers are 688,632,641,292

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

The LCM of 688,632,641,292 is 2543293136.

Find LCM of 688,632,641,292 with Prime Factorization


2 688, 632, 641, 292
2 344, 316, 641, 146
2 172, 158, 641, 73
86, 79, 641, 73

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

2 x 2 x 2 x 86 x 79 x 641 x 73 = 2543293136

Therefore, the lowest common multiple of 688,632,641,292 is 2543293136.

LCM Formula to Find Lowest Common Multiple of 688,632,641,292

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 632 x 641 x 292 = 81385380352

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

632 : 1, 2, 4, 8, 79, 158, 316, 632

641 : 1, 641

292 : 1, 2, 4, 73, 146, 292

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 688,632,641,292, is 1.

Now, the common factors can be found like this.

688:2x 2x 2x 2x 43

632:2x 2x 2x 79

641:641

292:2x 2x 73

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 2x 2x 2 = 32

Therefore, the value for common factors is 32.

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 = 81385380352/(1x32)

LCM = 81385380352/32

LCM = 2543293136

Thus, we can understand that the LCM of 688,632,641,292 is 2543293136.
