The LCM of 678,767,390,497 is 1292264610.

Find LCM of 678,767,390,497 with Prime Factorization


2 678, 767, 390, 497
3 339, 767, 195, 497
13 113, 767, 65, 497
113, 59, 5, 497

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

2 x 3 x 13 x 113 x 59 x 5 x 497 = 1292264610

Therefore, the lowest common multiple of 678,767,390,497 is 1292264610.

LCM Formula to Find Lowest Common Multiple of 678,767,390,497

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.

678 x 767 x 390 x 497 = 100796639580

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.

678 : 1, 2, 3, 6, 113, 226, 339, 678

767 : 1, 13, 59, 767

390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390

497 : 1, 7, 71, 497

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 678,767,390,497, is 1.

Now, the common factors can be found like this.

678:2x 3x 113

767:13x 59

390:2x 3x 5x 13

497:7x 71

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

2x 3x 13 = 78

Therefore, the value for common factors is 78.

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 = 100796639580/(1x78)

LCM = 100796639580/78

LCM = 1292264610

Thus, we can understand that the LCM of 678,767,390,497 is 1292264610.
