Given numbers are 836,728,661,884

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

The LCM of 836,728,661,884 is 1709732024.

Find LCM of 836,728,661,884 with Prime Factorization

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

2 x 2 x 13 x 209 x 14 x 661 x 17 = 1709732024

Therefore, the lowest common multiple of 836,728,661,884 is 1709732024.

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.

836 x 728 x 661 x 884 = 355624260992

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.

836 : 1, 2, 4, 11, 19, 22, 38, 44, 76, 209, 418, 836

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

661 : 1, 661

884 : 1, 2, 4, 13, 17, 26, 34, 52, 68, 221, 442, 884

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 836,728,661,884, is 1.

Now, the common factors can be found like this.

836:2x 2x 11x 19

728:2x 2x 2x 7x 13

661:661

884:2x 2x 13x 17

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 13 = 208

Therefore, the value for common factors is 208.

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 = 355624260992/(1x208)

LCM = 355624260992/208

LCM = 1709732024

Thus, we can understand that the LCM of 836,728,661,884 is 1709732024.
