Calculate the LCM of 651,655,920,740

Given numbers are 651,655,920,740

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

The LCM of 651,655,920,740 is 2902965240.

Find LCM of 651,655,920,740 with Prime Factorization


2 651, 655, 920, 740
2 651, 655, 460, 370
5 651, 655, 230, 185
651, 131, 46, 37

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

2 x 2 x 5 x 651 x 131 x 46 x 37 = 2902965240

Therefore, the lowest common multiple of 651,655,920,740 is 2902965240.

LCM Formula to Find Lowest Common Multiple of 651,655,920,740

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.

651 x 655 x 920 x 740 = 290296524000

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.

651 : 1, 3, 7, 21, 31, 93, 217, 651

655 : 1, 5, 131, 655

920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920

740 : 1, 2, 4, 5, 10, 20, 37, 74, 148, 185, 370, 740

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 651,655,920,740, is 1.

Now, the common factors can be found like this.

651:3x 7x 31

655:5x 131

920:2x 2x 2x 5x 23

740:2x 2x 5x 37

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 = 290296524000/(1x100)

LCM = 290296524000/100

LCM = 2902965240

Thus, we can understand that the LCM of 651,655,920,740 is 2902965240.
