Calculate the LCM of 347,988,690,912

Given numbers are 347,988,690,912

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

The LCM of 347,988,690,912 is 473113680.

Find LCM of 347,988,690,912 with Prime Factorization


2 347, 988, 690, 912
2 347, 494, 345, 456
3 347, 247, 345, 228
19 347, 247, 115, 76
347, 13, 115, 4

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

2 x 2 x 3 x 19 x 347 x 13 x 115 x 4 = 473113680

Therefore, the lowest common multiple of 347,988,690,912 is 473113680.

LCM Formula to Find Lowest Common Multiple of 347,988,690,912

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.

347 x 988 x 690 x 912 = 215739838080

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.

347 : 1, 347

988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988

690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690

912 : 1, 2, 3, 4, 6, 8, 12, 16, 19, 24, 38, 48, 57, 76, 114, 152, 228, 304, 456, 912

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 347,988,690,912, is 1.

Now, the common factors can be found like this.

347:347

988:2x 2x 13x 19

690:2x 3x 5x 23

912:2x 2x 2x 2x 3x 19

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 3x 19 = 456

Therefore, the value for common factors is 456.

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 = 215739838080/(1x456)

LCM = 215739838080/456

LCM = 473113680

Thus, we can understand that the LCM of 347,988,690,912 is 473113680.
