Calculate the LCM of 616,220,210

Given numbers are 616,220,210

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

The LCM of 616,220,210 is 9240.

Find LCM of 616,220,210 with Prime Factorization


2 616, 220, 210
2 308, 110, 105
5 154, 55, 105
7 154, 11, 21
11 22, 11, 3
2, 1, 3

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

2 x 2 x 5 x 7 x 11 x 2 x 1 x 3 = 9240

Therefore, the lowest common multiple of 616,220,210 is 9240.

LCM Formula to Find Lowest Common Multiple of 616,220,210

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.

616 x 220 x 210 = 28459200

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.

616 : 1, 2, 4, 7, 8, 11, 14, 22, 28, 44, 56, 77, 88, 154, 308, 616

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

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

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 616,220,210, is 2.

Now, the common factors can be found like this.

616:2x 2x 2x 7x 11

220:2x 2x 5x 11

210:2x 3x 5x 7

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 5x 7x 11 = 1540

Therefore, the value for common factors is 1540.

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 = 28459200/(2x1540)

LCM = 28459200/3080

LCM = 9240

Thus, we can understand that the LCM of 616,220,210 is 9240.
