Calculate the LCM of 394,158,788,697

Given numbers are 394,158,788,697

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

The LCM of 394,158,788,697 is 43389644.

Find LCM of 394,158,788,697 with Prime Factorization


2 394, 158, 788, 697
197 197, 79, 394, 697
1, 79, 2, 697

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

2 x 197 x 1 x 79 x 2 x 697 = 43389644

Therefore, the lowest common multiple of 394,158,788,697 is 43389644.

LCM Formula to Find Lowest Common Multiple of 394,158,788,697

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.

394 x 158 x 788 x 697 = 34191039472

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.

394 : 1, 2, 197, 394

158 : 1, 2, 79, 158

788 : 1, 2, 4, 197, 394, 788

697 : 1, 17, 41, 697

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 394,158,788,697, is 1.

Now, the common factors can be found like this.

394:2x 197

158:2x 79

788:2x 2x 197

697:17x 41

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 197 = 788

Therefore, the value for common factors is 788.

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 = 34191039472/(1x788)

LCM = 34191039472/788

LCM = 43389644

Thus, we can understand that the LCM of 394,158,788,697 is 43389644.
