Calculate the LCM of 538,689,772,661

Given numbers are 538,689,772,661

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

The LCM of 538,689,772,661 is 94578029572.

Find LCM of 538,689,772,661 with Prime Factorization


2 538, 689, 772, 661
269, 689, 386, 661

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

2 x 269 x 689 x 386 x 661 = 94578029572

Therefore, the lowest common multiple of 538,689,772,661 is 94578029572.

LCM Formula to Find Lowest Common Multiple of 538,689,772,661

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.

538 x 689 x 772 x 661 = 189156059144

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.

538 : 1, 2, 269, 538

689 : 1, 13, 53, 689

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

661 : 1, 661

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 538,689,772,661, is 1.

Now, the common factors can be found like this.

538:2x 269

689:13x 53

772:2x 2x 193

661:661

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 = 189156059144/(1x2)

LCM = 189156059144/2

LCM = 94578029572

Thus, we can understand that the LCM of 538,689,772,661 is 94578029572.
