Given numbers are 147,321,780,386

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

The LCM of 147,321,780,386 is 789281220.

Find LCM of 147,321,780,386 with Prime Factorization

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

2 x 3 x 49 x 107 x 130 x 193 = 789281220

Therefore, the lowest common multiple of 147,321,780,386 is 789281220.

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.

147 x 321 x 780 x 386 = 14207061960

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.

147 : 1, 3, 7, 21, 49, 147

321 : 1, 3, 107, 321

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

386 : 1, 2, 193, 386

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 147,321,780,386, is 1.

Now, the common factors can be found like this.

147:3x 7x 7

321:3x 107

780:2x 2x 3x 5x 13

386:2x 193

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

2x 3x 3 = 18

Therefore, the value for common factors is 18.

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 = 14207061960/(1x18)

LCM = 14207061960/18

LCM = 789281220

Thus, we can understand that the LCM of 147,321,780,386 is 789281220.
