Given numbers are 651,835,840,720

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

The LCM of 651,835,840,720 is 26092080.

Find LCM of 651,835,840,720 with Prime Factorization

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

2 x 2 x 2 x 3 x 5 x 7 x 31 x 167 x 1 x 6 = 26092080

Therefore, the lowest common multiple of 651,835,840,720 is 26092080.

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.

651 x 835 x 840 x 720 = 328760208000

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.

651 : 1, 3, 7, 21, 31, 93, 217, 651

835 : 1, 5, 167, 835

840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840

720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 651,835,840,720, is 1.

Now, the common factors can be found like this.

651:3x 7x 31

835:5x 167

840:2x 2x 2x 3x 5x 7

720:2x 2x 2x 2x 3x 3x 5

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 3x 3x 5x 5x 7 = 12600

Therefore, the value for common factors is 12600.

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 = 328760208000/(1x12600)

LCM = 328760208000/12600

LCM = 26092080

Thus, we can understand that the LCM of 651,835,840,720 is 26092080.
