Calculate the LCM of 394,874,969,654

Given numbers are 394,874,969,654

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

The LCM of 394,874,969,654 is 957137502.

Find LCM of 394,874,969,654 with Prime Factorization


2 394, 874, 969, 654
3 197, 437, 969, 327
19 197, 437, 323, 109
197, 23, 17, 109

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

2 x 3 x 19 x 197 x 23 x 17 x 109 = 957137502

Therefore, the lowest common multiple of 394,874,969,654 is 957137502.

LCM Formula to Find Lowest Common Multiple of 394,874,969,654

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.

394 x 874 x 969 x 654 = 218227350456

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.

394 : 1, 2, 197, 394

874 : 1, 2, 19, 23, 38, 46, 437, 874

969 : 1, 3, 17, 19, 51, 57, 323, 969

654 : 1, 2, 3, 6, 109, 218, 327, 654

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 394,874,969,654, is 1.

Now, the common factors can be found like this.

394:2x 197

874:2x 19x 23

969:3x 17x 19

654:2x 3x 109

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 3x 19 = 228

Therefore, the value for common factors is 228.

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 = 218227350456/(1x228)

LCM = 218227350456/228

LCM = 957137502

Thus, we can understand that the LCM of 394,874,969,654 is 957137502.
