Calculate the LCM of 210,116,161,557

Given numbers are 210,116,161,557

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

The LCM of 210,116,161,557 is 156037980.

Find LCM of 210,116,161,557 with Prime Factorization


2 210, 116, 161, 557
7 105, 58, 161, 557
15, 58, 23, 557

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

2 x 7 x 15 x 58 x 23 x 557 = 156037980

Therefore, the lowest common multiple of 210,116,161,557 is 156037980.

LCM Formula to Find Lowest Common Multiple of 210,116,161,557

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.

210 x 116 x 161 x 557 = 2184531720

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.

210 : 1, 2, 3, 5, 6, 7, 10, 14, 15, 21, 30, 35, 42, 70, 105, 210

116 : 1, 2, 4, 29, 58, 116

161 : 1, 7, 23, 161

557 : 1, 557

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 210,116,161,557, is 1.

Now, the common factors can be found like this.

210:2x 3x 5x 7

116:2x 2x 29

161:7x 23

557:557

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

2x 7 = 14

Therefore, the value for common factors is 14.

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 = 2184531720/(1x14)

LCM = 2184531720/14

LCM = 156037980

Thus, we can understand that the LCM of 210,116,161,557 is 156037980.
