Given numbers are 748,215,728,699

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

The LCM of 748,215,728,699 is 20459198760.

Find LCM of 748,215,728,699 with Prime Factorization

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

2 x 2 x 187 x 215 x 182 x 699 = 20459198760

Therefore, the lowest common multiple of 748,215,728,699 is 20459198760.

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.

748 x 215 x 728 x 699 = 81836795040

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.

748 : 1, 2, 4, 11, 17, 22, 34, 44, 68, 187, 374, 748

215 : 1, 5, 43, 215

728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728

699 : 1, 3, 233, 699

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 748,215,728,699, is 1.

Now, the common factors can be found like this.

748:2x 2x 11x 17

215:5x 43

728:2x 2x 2x 7x 13

699:3x 233

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 81836795040/(1x4)

LCM = 81836795040/4

LCM = 20459198760

Thus, we can understand that the LCM of 748,215,728,699 is 20459198760.
