Calculate the LCM of 724,924,640,698

Given numbers are 724,924,640,698

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

The LCM of 724,924,640,698 is 9338904960.

Find LCM of 724,924,640,698 with Prime Factorization


2 724, 924, 640, 698
2 362, 462, 320, 349
181, 231, 160, 349

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

2 x 2 x 181 x 231 x 160 x 349 = 9338904960

Therefore, the lowest common multiple of 724,924,640,698 is 9338904960.

LCM Formula to Find Lowest Common Multiple of 724,924,640,698

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.

724 x 924 x 640 x 698 = 298844958720

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.

724 : 1, 2, 4, 181, 362, 724

924 : 1, 2, 3, 4, 6, 7, 11, 12, 14, 21, 22, 28, 33, 42, 44, 66, 77, 84, 132, 154, 231, 308, 462, 924

640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640

698 : 1, 2, 349, 698

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 724,924,640,698, is 2.

Now, the common factors can be found like this.

724:2x 2x 181

924:2x 2x 3x 7x 11

640:2x 2x 2x 2x 2x 2x 2x 5

698:2x 349

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 2 = 16

Therefore, the value for common factors is 16.

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 = 298844958720/(2x16)

LCM = 298844958720/32

LCM = 9338904960

Thus, we can understand that the LCM of 724,924,640,698 is 9338904960.
