Given numbers are 917,739,763,420

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

The LCM of 917,739,763,420 is 4431916020.

Find LCM of 917,739,763,420 with Prime Factorization

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

7 x 131 x 739 x 109 x 60 = 4431916020

Therefore, the lowest common multiple of 917,739,763,420 is 4431916020.

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.

917 x 739 x 763 x 420 = 217163884980

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.

917 : 1, 7, 131, 917

739 : 1, 739

763 : 1, 7, 109, 763

420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 917,739,763,420, is 1.

Now, the common factors can be found like this.

917:7x 131

739:739

763:7x 109

420:2x 2x 3x 5x 7

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

7x 7 = 49

Therefore, the value for common factors is 49.

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 = 217163884980/(1x49)

LCM = 217163884980/49

LCM = 4431916020

Thus, we can understand that the LCM of 917,739,763,420 is 4431916020.
