Calculate the LCM of 916,220,697,388

Given numbers are 916,220,697,388

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

The LCM of 916,220,697,388 is 3406141420.

Find LCM of 916,220,697,388 with Prime Factorization


2 916, 220, 697, 388
2 458, 110, 697, 194
229, 55, 697, 97

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

2 x 2 x 229 x 55 x 697 x 97 = 3406141420

Therefore, the lowest common multiple of 916,220,697,388 is 3406141420.

LCM Formula to Find Lowest Common Multiple of 916,220,697,388

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.

916 x 220 x 697 x 388 = 54498262720

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.

916 : 1, 2, 4, 229, 458, 916

220 : 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220

697 : 1, 17, 41, 697

388 : 1, 2, 4, 97, 194, 388

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 916,220,697,388, is 1.

Now, the common factors can be found like this.

916:2x 2x 229

220:2x 2x 5x 11

697:17x 41

388:2x 2x 97

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 = 54498262720/(1x16)

LCM = 54498262720/16

LCM = 3406141420

Thus, we can understand that the LCM of 916,220,697,388 is 3406141420.
