The LCM of 975,811,551,280 is 24398610600.

Find LCM of 975,811,551,280 with Prime Factorization


5 975, 811, 551, 280
195, 811, 551, 56

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

5 x 195 x 811 x 551 x 56 = 24398610600

Therefore, the lowest common multiple of 975,811,551,280 is 24398610600.

LCM Formula to Find Lowest Common Multiple of 975,811,551,280

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.

975 x 811 x 551 x 280 = 121993053000

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.

975 : 1, 3, 5, 13, 15, 25, 39, 65, 75, 195, 325, 975

811 : 1, 811

551 : 1, 19, 29, 551

280 : 1, 2, 4, 5, 7, 8, 10, 14, 20, 28, 35, 40, 56, 70, 140, 280

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 975,811,551,280, is 1.

Now, the common factors can be found like this.

975:3x 5x 5x 13

811:811

551:19x 29

280:2x 2x 2x 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.

5 = 5

Therefore, the value for common factors is 5.

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 = 121993053000/(1x5)

LCM = 121993053000/5

LCM = 24398610600

Thus, we can understand that the LCM of 975,811,551,280 is 24398610600.
