Given numbers are 697,715,121,286

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

The LCM of 697,715,121,286 is 10963810.

Find LCM of 697,715,121,286 with Prime Factorization

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

11 x 13 x 697 x 5 x 11 x 2 = 10963810

Therefore, the lowest common multiple of 697,715,121,286 is 10963810.

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.

697 x 715 x 121 x 286 = 17246073130

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.

697 : 1, 17, 41, 697

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

121 : 1, 11, 121

286 : 1, 2, 11, 13, 22, 26, 143, 286

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 697,715,121,286, is 1.

Now, the common factors can be found like this.

697:17x 41

715:5x 11x 13

121:11x 11

286:2x 11x 13

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

11x 11x 13 = 1573

Therefore, the value for common factors is 1573.

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 = 17246073130/(1x1573)

LCM = 17246073130/1573

LCM = 10963810

Thus, we can understand that the LCM of 697,715,121,286 is 10963810.
