Given numbers are 157,390,780,299

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

The LCM of 157,390,780,299 is 2816580.

Find LCM of 157,390,780,299 with Prime Factorization

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

2 x 3 x 5 x 13 x 157 x 1 x 2 x 23 = 2816580

Therefore, the lowest common multiple of 157,390,780,299 is 2816580.

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.

157 x 390 x 780 x 299 = 14280060600

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.

157 : 1, 157

390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390

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

299 : 1, 13, 23, 299

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 157,390,780,299, is 1.

Now, the common factors can be found like this.

157:157

390:2x 3x 5x 13

780:2x 2x 3x 5x 13

299:13x 23

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

2x 3x 5x 13x 13 = 5070

Therefore, the value for common factors is 5070.

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 = 14280060600/(1x5070)

LCM = 14280060600/5070

LCM = 2816580

Thus, we can understand that the LCM of 157,390,780,299 is 2816580.
