Calculate the LCM of 438,512,757,743,631

Given numbers are 438,512,757,743,631

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

The LCM of 438,512,757,743,631 is 39794965114368.

Find LCM of 438,512,757,743,631 with Prime Factorization


2 438, 512, 757, 743, 631
219, 256, 757, 743, 631

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

2 x 219 x 256 x 757 x 743 x 631 = 39794965114368

Therefore, the lowest common multiple of 438,512,757,743,631 is 39794965114368.

LCM Formula to Find Lowest Common Multiple of 438,512,757,743,631

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.

438 x 512 x 757 x 743 x 631 = 79589930228736

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.

438 : 1, 2, 3, 6, 73, 146, 219, 438

512 : 1, 2, 4, 8, 16, 32, 64, 128, 256, 512

757 : 1, 757

743 : 1, 743

631 : 1, 631

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 438,512,757,743,631, is 1.

Now, the common factors can be found like this.

438:2x 3x 73

512:2x 2x 2x 2x 2x 2x 2x 2x 2

757:757

743:743

631:631

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 = 79589930228736/(1x2)

LCM = 79589930228736/2

LCM = 39794965114368

Thus, we can understand that the LCM of 438,512,757,743,631 is 39794965114368.
