Calculate the LCM of 177,780,900,788

Given numbers are 177,780,900,788

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

The LCM of 177,780,900,788 is 135989100.

Find LCM of 177,780,900,788 with Prime Factorization


2 177, 780, 900, 788
2 177, 390, 450, 394
3 177, 195, 225, 197
5 59, 65, 75, 197
59, 13, 15, 197

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

2 x 2 x 3 x 5 x 59 x 13 x 15 x 197 = 135989100

Therefore, the lowest common multiple of 177,780,900,788 is 135989100.

LCM Formula to Find Lowest Common Multiple of 177,780,900,788

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.

177 x 780 x 900 x 788 = 97912152000

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.

177 : 1, 3, 59, 177

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

900 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 25, 30, 36, 45, 50, 60, 75, 90, 100, 150, 180, 225, 300, 450, 900

788 : 1, 2, 4, 197, 394, 788

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 177,780,900,788, is 1.

Now, the common factors can be found like this.

177:3x 59

780:2x 2x 3x 5x 13

900:2x 2x 3x 3x 5x 5

788:2x 2x 197

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 = 97912152000/(1x720)

LCM = 97912152000/720

LCM = 135989100

Thus, we can understand that the LCM of 177,780,900,788 is 135989100.
