Given numbers are 157,521,178,102,740

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

The LCM of 157,521,178,102,740 is 274744671420.

Find LCM of 157,521,178,102,740 with Prime Factorization

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

2 x 157 x 521 x 89 x 51 x 370 = 274744671420

Therefore, the lowest common multiple of 157,521,178,102,740 is 274744671420.

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 521 x 178 x 102 x 740 = 1098978685680

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

521 : 1, 521

178 : 1, 2, 89, 178

102 : 1, 2, 3, 6, 17, 34, 51, 102

740 : 1, 2, 4, 5, 10, 20, 37, 74, 148, 185, 370, 740

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 157,521,178,102,740, is 1.

Now, the common factors can be found like this.

157:157

521:521

178:2x 89

102:2x 3x 17

740:2x 2x 5x 37

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 1098978685680/(1x4)

LCM = 1098978685680/4

LCM = 274744671420

Thus, we can understand that the LCM of 157,521,178,102,740 is 274744671420.
