The LCM of 126,418,957,290 is 3818430.

Find LCM of 126,418,957,290 with Prime Factorization


2 126, 418, 957, 290
3 63, 209, 957, 145
11 21, 209, 319, 145
29 21, 19, 29, 145
21, 19, 1, 5

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

2 x 3 x 11 x 29 x 21 x 19 x 1 x 5 = 3818430

Therefore, the lowest common multiple of 126,418,957,290 is 3818430.

LCM Formula to Find Lowest Common Multiple of 126,418,957,290

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.

126 x 418 x 957 x 290 = 14616950040

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.

126 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 42, 63, 126

418 : 1, 2, 11, 19, 22, 38, 209, 418

957 : 1, 3, 11, 29, 33, 87, 319, 957

290 : 1, 2, 5, 10, 29, 58, 145, 290

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 126,418,957,290, is 1.

Now, the common factors can be found like this.

126:2x 3x 3x 7

418:2x 11x 19

957:3x 11x 29

290:2x 5x 29

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 11x 29 = 3828

Therefore, the value for common factors is 3828.

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 = 14616950040/(1x3828)

LCM = 14616950040/3828

LCM = 3818430

Thus, we can understand that the LCM of 126,418,957,290 is 3818430.
