The LCM of 838,372,946,989 is 1695687972.

Find LCM of 838,372,946,989 with Prime Factorization


2 838, 372, 946, 989
43 419, 186, 473, 989
419, 186, 11, 23

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

2 x 43 x 419 x 186 x 11 x 23 = 1695687972

Therefore, the lowest common multiple of 838,372,946,989 is 1695687972.

LCM Formula to Find Lowest Common Multiple of 838,372,946,989

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.

838 x 372 x 946 x 989 = 291658331184

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.

838 : 1, 2, 419, 838

372 : 1, 2, 3, 4, 6, 12, 31, 62, 93, 124, 186, 372

946 : 1, 2, 11, 22, 43, 86, 473, 946

989 : 1, 23, 43, 989

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 838,372,946,989, is 1.

Now, the common factors can be found like this.

838:2x 419

372:2x 2x 3x 31

946:2x 11x 43

989:23x 43

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 43 = 172

Therefore, the value for common factors is 172.

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 = 291658331184/(1x172)

LCM = 291658331184/172

LCM = 1695687972

Thus, we can understand that the LCM of 838,372,946,989 is 1695687972.
