Given numbers are 155,121,397,713

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

The LCM of 155,121,397,713 is 171251905.

Find LCM of 155,121,397,713 with Prime Factorization

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

31 x 5 x 121 x 397 x 23 = 171251905

Therefore, the lowest common multiple of 155,121,397,713 is 171251905.

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.

155 x 121 x 397 x 713 = 5308809055

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.

155 : 1, 5, 31, 155

121 : 1, 11, 121

397 : 1, 397

713 : 1, 23, 31, 713

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 155,121,397,713, is 1.

Now, the common factors can be found like this.

155:5x 31

121:11x 11

397:397

713:23x 31

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

31 = 31

Therefore, the value for common factors is 31.

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 = 5308809055/(1x31)

LCM = 5308809055/31

LCM = 171251905

Thus, we can understand that the LCM of 155,121,397,713 is 171251905.
