Given numbers are 403,970,780,737

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

The LCM of 403,970,780,737 is 1728604020.

Find LCM of 403,970,780,737 with Prime Factorization

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

2 x 5 x 13 x 31 x 97 x 6 x 737 = 1728604020

Therefore, the lowest common multiple of 403,970,780,737 is 1728604020.

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.

403 x 970 x 780 x 737 = 224718522600

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.

403 : 1, 13, 31, 403

970 : 1, 2, 5, 10, 97, 194, 485, 970

780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780

737 : 1, 11, 67, 737

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 403,970,780,737, is 1.

Now, the common factors can be found like this.

403:13x 31

970:2x 5x 97

780:2x 2x 3x 5x 13

737:11x 67

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

2x 5x 13 = 130

Therefore, the value for common factors is 130.

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 = 224718522600/(1x130)

LCM = 224718522600/130

LCM = 1728604020

Thus, we can understand that the LCM of 403,970,780,737 is 1728604020.
