Given numbers are 668,130,678,602,728

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

The LCM of 668,130,678,602,728 is 8861066760.

Find LCM of 668,130,678,602,728 with Prime Factorization

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

2 x 2 x 7 x 13 x 167 x 5 x 339 x 43 x 2 = 8861066760

Therefore, the lowest common multiple of 668,130,678,602,728 is 8861066760.

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.

668 x 130 x 678 x 602 x 728 = 25803426405120

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.

668 : 1, 2, 4, 167, 334, 668

130 : 1, 2, 5, 10, 13, 26, 65, 130

678 : 1, 2, 3, 6, 113, 226, 339, 678

602 : 1, 2, 7, 14, 43, 86, 301, 602

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

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 668,130,678,602,728, is 2.

Now, the common factors can be found like this.

668:2x 2x 167

130:2x 5x 13

678:2x 3x 113

602:2x 7x 43

728:2x 2x 2x 7x 13

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 2x 7x 13 = 1456

Therefore, the value for common factors is 1456.

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 = 25803426405120/(2x1456)

LCM = 25803426405120/2912

LCM = 8861066760

Thus, we can understand that the LCM of 668,130,678,602,728 is 8861066760.
