Calculate the LCM of 620,415,538,630

Given numbers are 620,415,538,630

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

The LCM of 620,415,538,630 is 872092620.

Find LCM of 620,415,538,630 with Prime Factorization


2 620, 415, 538, 630
5 310, 415, 269, 315
62, 83, 269, 63

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

2 x 5 x 62 x 83 x 269 x 63 = 872092620

Therefore, the lowest common multiple of 620,415,538,630 is 872092620.

LCM Formula to Find Lowest Common Multiple of 620,415,538,630

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.

620 x 415 x 538 x 630 = 87209262000

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.

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

415 : 1, 5, 83, 415

538 : 1, 2, 269, 538

630 : 1, 2, 3, 5, 6, 7, 9, 10, 14, 15, 18, 21, 30, 35, 42, 45, 63, 70, 90, 105, 126, 210, 315, 630

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 620,415,538,630, is 1.

Now, the common factors can be found like this.

620:2x 2x 5x 31

415:5x 83

538:2x 269

630:2x 3x 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 5 = 100

Therefore, the value for common factors is 100.

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 = 87209262000/(1x100)

LCM = 87209262000/100

LCM = 872092620

Thus, we can understand that the LCM of 620,415,538,630 is 872092620.
