Given numbers are 820,156,247,478,980

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

The LCM of 820,156,247,478,980 is 7115837820.

Find LCM of 820,156,247,478,980 with Prime Factorization

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

2 x 2 x 5 x 13 x 41 x 3 x 19 x 239 x 49 = 7115837820

Therefore, the lowest common multiple of 820,156,247,478,980 is 7115837820.

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.

820 x 156 x 247 x 478 x 980 = 14800942665600

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.

820 : 1, 2, 4, 5, 10, 20, 41, 82, 164, 205, 410, 820

156 : 1, 2, 3, 4, 6, 12, 13, 26, 39, 52, 78, 156

247 : 1, 13, 19, 247

478 : 1, 2, 239, 478

980 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 49, 70, 98, 140, 196, 245, 490, 980

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 820,156,247,478,980, is 1.

Now, the common factors can be found like this.

820:2x 2x 5x 41

156:2x 2x 3x 13

247:13x 19

478:2x 239

980:2x 2x 5x 7x 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 2x 2x 2x 5x 13 = 2080

Therefore, the value for common factors is 2080.

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 = 14800942665600/(1x2080)

LCM = 14800942665600/2080

LCM = 7115837820

Thus, we can understand that the LCM of 820,156,247,478,980 is 7115837820.
