Calculate the LCM of 220,718,278,161

Given numbers are 220,718,278,161

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

The LCM of 220,718,278,161 is 1767493420.

Find LCM of 220,718,278,161 with Prime Factorization


2 220, 718, 278, 161
110, 359, 139, 161

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

2 x 110 x 359 x 139 x 161 = 1767493420

Therefore, the lowest common multiple of 220,718,278,161 is 1767493420.

LCM Formula to Find Lowest Common Multiple of 220,718,278,161

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.

220 x 718 x 278 x 161 = 7069973680

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.

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

718 : 1, 2, 359, 718

278 : 1, 2, 139, 278

161 : 1, 7, 23, 161

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 220,718,278,161, is 1.

Now, the common factors can be found like this.

220:2x 2x 5x 11

718:2x 359

278:2x 139

161:7x 23

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 = 7069973680/(1x4)

LCM = 7069973680/4

LCM = 1767493420

Thus, we can understand that the LCM of 220,718,278,161 is 1767493420.
