Calculate the LCM of 607,420,618,421

Given numbers are 607,420,618,421

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

The LCM of 607,420,618,421 is 11054963220.

Find LCM of 607,420,618,421 with Prime Factorization


2 607, 420, 618, 421
3 607, 210, 309, 421
607, 70, 103, 421

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

2 x 3 x 607 x 70 x 103 x 421 = 11054963220

Therefore, the lowest common multiple of 607,420,618,421 is 11054963220.

LCM Formula to Find Lowest Common Multiple of 607,420,618,421

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.

607 x 420 x 618 x 421 = 66329779320

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.

607 : 1, 607

420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420

618 : 1, 2, 3, 6, 103, 206, 309, 618

421 : 1, 421

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 607,420,618,421, is 1.

Now, the common factors can be found like this.

607:607

420:2x 2x 3x 5x 7

618:2x 3x 103

421:421

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

2x 3 = 6

Therefore, the value for common factors is 6.

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 = 66329779320/(1x6)

LCM = 66329779320/6

LCM = 11054963220

Thus, we can understand that the LCM of 607,420,618,421 is 11054963220.
