Calculate the LCM of 939,615,437,646

Given numbers are 939,615,437,646

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

The LCM of 939,615,437,646 is 2860090710.

Find LCM of 939,615,437,646 with Prime Factorization


3 939, 615, 437, 646
19 313, 205, 437, 646
313, 205, 23, 34

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

3 x 19 x 313 x 205 x 23 x 34 = 2860090710

Therefore, the lowest common multiple of 939,615,437,646 is 2860090710.

LCM Formula to Find Lowest Common Multiple of 939,615,437,646

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.

939 x 615 x 437 x 646 = 163025170470

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.

939 : 1, 3, 313, 939

615 : 1, 3, 5, 15, 41, 123, 205, 615

437 : 1, 19, 23, 437

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 939,615,437,646, is 1.

Now, the common factors can be found like this.

939:3x 313

615:3x 5x 41

437:19x 23

646:2x 17x 19

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

3x 19 = 57

Therefore, the value for common factors is 57.

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 = 163025170470/(1x57)

LCM = 163025170470/57

LCM = 2860090710

Thus, we can understand that the LCM of 939,615,437,646 is 2860090710.
