The LCM of 126,943,646,389 is 14929125246.

Find LCM of 126,943,646,389 with Prime Factorization


2 126, 943, 646, 389
63, 943, 323, 389

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

2 x 63 x 943 x 323 x 389 = 14929125246

Therefore, the lowest common multiple of 126,943,646,389 is 14929125246.

LCM Formula to Find Lowest Common Multiple of 126,943,646,389

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 943 x 646 x 389 = 29858250492

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

943 : 1, 23, 41, 943

646 : 1, 2, 17, 19, 34, 38, 323, 646

389 : 1, 389

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 126,943,646,389, is 1.

Now, the common factors can be found like this.

126:2x 3x 3x 7

943:23x 41

646:2x 17x 19

389:389

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2 = 2

Therefore, the value for common factors is 2.

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 = 29858250492/(1x2)

LCM = 29858250492/2

LCM = 14929125246

Thus, we can understand that the LCM of 126,943,646,389 is 14929125246.
