Given numbers are 157,209,709,471

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

The LCM of 157,209,709,471 is 69793251.

Find LCM of 157,209,709,471 with Prime Factorization

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

157 x 1 x 209 x 709 x 3 = 69793251

Therefore, the lowest common multiple of 157,209,709,471 is 69793251.

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 209 x 709 x 471 = 10957540407

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

209 : 1, 11, 19, 209

709 : 1, 709

471 : 1, 3, 157, 471

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 157,209,709,471, is 1.

Now, the common factors can be found like this.

157:157

209:11x 19

709:709

471:3x 157

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

157 = 157

Therefore, the value for common factors is 157.

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 = 10957540407/(1x157)

LCM = 10957540407/157

LCM = 69793251

Thus, we can understand that the LCM of 157,209,709,471 is 69793251.
