Given numbers are 746,790,780,854

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

The LCM of 746,790,780,854 is 9814279020.

Find LCM of 746,790,780,854 with Prime Factorization

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

2 x 5 x 373 x 79 x 78 x 427 = 9814279020

Therefore, the lowest common multiple of 746,790,780,854 is 9814279020.

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.

746 x 790 x 780 x 854 = 392571160800

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.

746 : 1, 2, 373, 746

790 : 1, 2, 5, 10, 79, 158, 395, 790

780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780

854 : 1, 2, 7, 14, 61, 122, 427, 854

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 746,790,780,854, is 2.

Now, the common factors can be found like this.

746:2x 373

790:2x 5x 79

780:2x 2x 3x 5x 13

854:2x 7x 61

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 5 = 20

Therefore, the value for common factors is 20.

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 = 392571160800/(2x20)

LCM = 392571160800/40

LCM = 9814279020

Thus, we can understand that the LCM of 746,790,780,854 is 9814279020.
