Given numbers are 702,620,286,280

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

The LCM of 702,620,286,280 is 33513480.

Find LCM of 702,620,286,280 with Prime Factorization

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

2 x 2 x 5 x 13 x 27 x 31 x 11 x 14 = 33513480

Therefore, the lowest common multiple of 702,620,286,280 is 33513480.

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.

702 x 620 x 286 x 280 = 34854019200

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.

702 : 1, 2, 3, 6, 9, 13, 18, 26, 27, 39, 54, 78, 117, 234, 351, 702

620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620

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

280 : 1, 2, 4, 5, 7, 8, 10, 14, 20, 28, 35, 40, 56, 70, 140, 280

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 702,620,286,280, is 2.

Now, the common factors can be found like this.

702:2x 3x 3x 3x 13

620:2x 2x 5x 31

286:2x 11x 13

280:2x 2x 2x 5x 7

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

2x 2x 2x 5x 13 = 520

Therefore, the value for common factors is 520.

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 = 34854019200/(2x520)

LCM = 34854019200/1040

LCM = 33513480

Thus, we can understand that the LCM of 702,620,286,280 is 33513480.
