Calculate the LCM of 446,385,790,294

Given numbers are 446,385,790,294

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

The LCM of 446,385,790,294 is 284866890.

Find LCM of 446,385,790,294 with Prime Factorization


2 446, 385, 790, 294
5 223, 385, 395, 147
7 223, 77, 79, 147
223, 11, 79, 21

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

2 x 5 x 7 x 223 x 11 x 79 x 21 = 284866890

Therefore, the lowest common multiple of 446,385,790,294 is 284866890.

LCM Formula to Find Lowest Common Multiple of 446,385,790,294

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.

446 x 385 x 790 x 294 = 39881364600

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.

446 : 1, 2, 223, 446

385 : 1, 5, 7, 11, 35, 55, 77, 385

790 : 1, 2, 5, 10, 79, 158, 395, 790

294 : 1, 2, 3, 6, 7, 14, 21, 42, 49, 98, 147, 294

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 446,385,790,294, is 1.

Now, the common factors can be found like this.

446:2x 223

385:5x 7x 11

790:2x 5x 79

294:2x 3x 7x 7

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 5x 7 = 140

Therefore, the value for common factors is 140.

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 = 39881364600/(1x140)

LCM = 39881364600/140

LCM = 284866890

Thus, we can understand that the LCM of 446,385,790,294 is 284866890.
