Calculate the LCM of 351,880,220,349,646

Given numbers are 351,880,220,349,646

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

The LCM of 351,880,220,349,646 is 34819115760.

Find LCM of 351,880,220,349,646 with Prime Factorization


2 351, 880, 220, 349, 646
2 351, 440, 110, 349, 323
5 351, 220, 55, 349, 323
11 351, 44, 11, 349, 323
351, 4, 1, 349, 323

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

2 x 2 x 5 x 11 x 351 x 4 x 1 x 349 x 323 = 34819115760

Therefore, the lowest common multiple of 351,880,220,349,646 is 34819115760.

LCM Formula to Find Lowest Common Multiple of 351,880,220,349,646

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.

351 x 880 x 220 x 349 x 646 = 15320410934400

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.

351 : 1, 3, 9, 13, 27, 39, 117, 351

880 : 1, 2, 4, 5, 8, 10, 11, 16, 20, 22, 40, 44, 55, 80, 88, 110, 176, 220, 440, 880

220 : 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220

349 : 1, 349

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 351,880,220,349,646, is 1.

Now, the common factors can be found like this.

351:3x 3x 3x 13

880:2x 2x 2x 2x 5x 11

220:2x 2x 5x 11

349:349

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.

2x 2x 2x 5x 11 = 440

Therefore, the value for common factors is 440.

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 = 15320410934400/(1x440)

LCM = 15320410934400/440

LCM = 34819115760

Thus, we can understand that the LCM of 351,880,220,349,646 is 34819115760.
