Given numbers are 221,715,438,397,293

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

The LCM of 221,715,438,397,293 is 619280208690.

Find LCM of 221,715,438,397,293 with Prime Factorization

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

13 x 17 x 55 x 438 x 397 x 293 = 619280208690

Therefore, the lowest common multiple of 221,715,438,397,293 is 619280208690.

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.

221 x 715 x 438 x 397 x 293 = 8050642712970

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.

221 : 1, 13, 17, 221

715 : 1, 5, 11, 13, 55, 65, 143, 715

438 : 1, 2, 3, 6, 73, 146, 219, 438

397 : 1, 397

293 : 1, 293

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 221,715,438,397,293, is 1.

Now, the common factors can be found like this.

221:13x 17

715:5x 11x 13

438:2x 3x 73

397:397

293:293

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

13 = 13

Therefore, the value for common factors is 13.

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 = 8050642712970/(1x13)

LCM = 8050642712970/13

LCM = 619280208690

Thus, we can understand that the LCM of 221,715,438,397,293 is 619280208690.
