Calculate the LCM of 647,448,575,553

Given numbers are 647,448,575,553

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

The LCM of 647,448,575,553 is 13166708800.

Find LCM of 647,448,575,553 with Prime Factorization


7 647, 448, 575, 553
647, 64, 575, 79

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

7 x 647 x 64 x 575 x 79 = 13166708800

Therefore, the lowest common multiple of 647,448,575,553 is 13166708800.

LCM Formula to Find Lowest Common Multiple of 647,448,575,553

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.

647 x 448 x 575 x 553 = 92166961600

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.

647 : 1, 647

448 : 1, 2, 4, 7, 8, 14, 16, 28, 32, 56, 64, 112, 224, 448

575 : 1, 5, 23, 25, 115, 575

553 : 1, 7, 79, 553

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 647,448,575,553, is 1.

Now, the common factors can be found like this.

647:647

448:2x 2x 2x 2x 2x 2x 7

575:5x 5x 23

553:7x 79

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

7 = 7

Therefore, the value for common factors is 7.

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 = 92166961600/(1x7)

LCM = 92166961600/7

LCM = 13166708800

Thus, we can understand that the LCM of 647,448,575,553 is 13166708800.
