Given numbers are 770,720,418,908

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

The LCM of 770,720,418,908 is 239112720.

Find LCM of 770,720,418,908 with Prime Factorization

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

2 x 2 x 5 x 11 x 7 x 36 x 19 x 227 = 239112720

Therefore, the lowest common multiple of 770,720,418,908 is 239112720.

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.

770 x 720 x 418 x 908 = 210419193600

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.

770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770

720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720

418 : 1, 2, 11, 19, 22, 38, 209, 418

908 : 1, 2, 4, 227, 454, 908

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 770,720,418,908, is 2.

Now, the common factors can be found like this.

770:2x 5x 7x 11

720:2x 2x 2x 2x 3x 3x 5

418:2x 11x 19

908:2x 2x 227

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 = 210419193600/(2x440)

LCM = 210419193600/880

LCM = 239112720

Thus, we can understand that the LCM of 770,720,418,908 is 239112720.
