Given numbers are 678,197,494,834,947

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

The LCM of 678,197,494,834,947 is 4342678239666.

Find LCM of 678,197,494,834,947 with Prime Factorization

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

2 x 3 x 113 x 197 x 247 x 139 x 947 = 4342678239666

Therefore, the lowest common multiple of 678,197,494,834,947 is 4342678239666.

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 197 x 494 x 834 x 947 = 52112138875992

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

197 : 1, 197

494 : 1, 2, 13, 19, 26, 38, 247, 494

834 : 1, 2, 3, 6, 139, 278, 417, 834

947 : 1, 947

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 678,197,494,834,947, is 1.

Now, the common factors can be found like this.

678:2x 3x 113

197:197

494:2x 13x 19

834:2x 3x 139

947:947

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 3 = 12

Therefore, the value for common factors is 12.

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 = 52112138875992/(1x12)

LCM = 52112138875992/12

LCM = 4342678239666

Thus, we can understand that the LCM of 678,197,494,834,947 is 4342678239666.
