Calculate the LCM of 616,620,571,858

Given numbers are 616,620,571,858

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

The LCM of 616,620,571,858 is 2126244120.

Find LCM of 616,620,571,858 with Prime Factorization


2 616, 620, 571, 858
2 308, 310, 571, 429
11 154, 155, 571, 429
14, 155, 571, 39

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

2 x 2 x 11 x 14 x 155 x 571 x 39 = 2126244120

Therefore, the lowest common multiple of 616,620,571,858 is 2126244120.

LCM Formula to Find Lowest Common Multiple of 616,620,571,858

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 620 x 571 x 858 = 187109482560

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

620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620

571 : 1, 571

858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 616,620,571,858, is 1.

Now, the common factors can be found like this.

616:2x 2x 2x 7x 11

620:2x 2x 5x 31

571:571

858:2x 3x 11x 13

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 11 = 88

Therefore, the value for common factors is 88.

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 = 187109482560/(1x88)

LCM = 187109482560/88

LCM = 2126244120

Thus, we can understand that the LCM of 616,620,571,858 is 2126244120.
