Given numbers are 702,696,721,798

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

The LCM of 702,696,721,798 is 1115536968.

Find LCM of 702,696,721,798 with Prime Factorization

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

2 x 3 x 7 x 117 x 116 x 103 x 19 = 1115536968

Therefore, the lowest common multiple of 702,696,721,798 is 1115536968.

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 696 x 721 x 798 = 281115315936

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

696 : 1, 2, 3, 4, 6, 8, 12, 24, 29, 58, 87, 116, 174, 232, 348, 696

721 : 1, 7, 103, 721

798 : 1, 2, 3, 6, 7, 14, 19, 21, 38, 42, 57, 114, 133, 266, 399, 798

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 702,696,721,798, is 1.

Now, the common factors can be found like this.

702:2x 3x 3x 3x 13

696:2x 2x 2x 3x 29

721:7x 103

798:2x 3x 7x 19

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 3x 3x 7 = 252

Therefore, the value for common factors is 252.

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 = 281115315936/(1x252)

LCM = 281115315936/252

LCM = 1115536968

Thus, we can understand that the LCM of 702,696,721,798 is 1115536968.
