Calculate the LCM of 772,989,638,434

Given numbers are 772,989,638,434

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

The LCM of 772,989,638,434 is 52852314284.

Find LCM of 772,989,638,434 with Prime Factorization


2 772, 989, 638, 434
386, 989, 319, 217

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

2 x 386 x 989 x 319 x 217 = 52852314284

Therefore, the lowest common multiple of 772,989,638,434 is 52852314284.

LCM Formula to Find Lowest Common Multiple of 772,989,638,434

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.

772 x 989 x 638 x 434 = 211409257136

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.

772 : 1, 2, 4, 193, 386, 772

989 : 1, 23, 43, 989

638 : 1, 2, 11, 22, 29, 58, 319, 638

434 : 1, 2, 7, 14, 31, 62, 217, 434

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 772,989,638,434, is 1.

Now, the common factors can be found like this.

772:2x 2x 193

989:23x 43

638:2x 11x 29

434:2x 7x 31

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 211409257136/(1x4)

LCM = 211409257136/4

LCM = 52852314284

Thus, we can understand that the LCM of 772,989,638,434 is 52852314284.
