Given numbers are 652,780,420,303

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

The LCM of 652,780,420,303 is 89887980.

Find LCM of 652,780,420,303 with Prime Factorization

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

2 x 2 x 3 x 5 x 163 x 13 x 7 x 101 = 89887980

Therefore, the lowest common multiple of 652,780,420,303 is 89887980.

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.

652 x 780 x 420 x 303 = 64719345600

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.

652 : 1, 2, 4, 163, 326, 652

780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780

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

303 : 1, 3, 101, 303

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 652,780,420,303, is 1.

Now, the common factors can be found like this.

652:2x 2x 163

780:2x 2x 3x 5x 13

420:2x 2x 3x 5x 7

303:3x 101

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 2x 3x 3x 5 = 720

Therefore, the value for common factors is 720.

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 = 64719345600/(1x720)

LCM = 64719345600/720

LCM = 89887980

Thus, we can understand that the LCM of 652,780,420,303 is 89887980.
