Calculate the LCM of 627,661,247,420

Given numbers are 627,661,247,420

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

The LCM of 627,661,247,420 is 754293540.

Find LCM of 627,661,247,420 with Prime Factorization


3 627, 661, 247, 420
19 209, 661, 247, 140
11, 661, 13, 140

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

3 x 19 x 11 x 661 x 13 x 140 = 754293540

Therefore, the lowest common multiple of 627,661,247,420 is 754293540.

LCM Formula to Find Lowest Common Multiple of 627,661,247,420

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.

627 x 661 x 247 x 420 = 42994731780

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.

627 : 1, 3, 11, 19, 33, 57, 209, 627

661 : 1, 661

247 : 1, 13, 19, 247

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 627,661,247,420, is 1.

Now, the common factors can be found like this.

627:3x 11x 19

661:661

247:13x 19

420:2x 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.

3x 19 = 57

Therefore, the value for common factors is 57.

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 = 42994731780/(1x57)

LCM = 42994731780/57

LCM = 754293540

Thus, we can understand that the LCM of 627,661,247,420 is 754293540.
