Given numbers are 121,690,816,440,427

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

The LCM of 121,690,816,440,427 is 4848431280.

Find LCM of 121,690,816,440,427 with Prime Factorization

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

2 x 2 x 2 x 3 x 5 x 11 x 1 x 23 x 34 x 11 x 427 = 4848431280

Therefore, the lowest common multiple of 121,690,816,440,427 is 4848431280.

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.

121 x 690 x 816 x 440 x 427 = 12799858579200

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.

121 : 1, 11, 121

690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690

816 : 1, 2, 3, 4, 6, 8, 12, 16, 17, 24, 34, 48, 51, 68, 102, 136, 204, 272, 408, 816

440 : 1, 2, 4, 5, 8, 10, 11, 20, 22, 40, 44, 55, 88, 110, 220, 440

427 : 1, 7, 61, 427

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 121,690,816,440,427, is 1.

Now, the common factors can be found like this.

121:11x 11

690:2x 3x 5x 23

816:2x 2x 2x 2x 3x 17

440:2x 2x 2x 5x 11

427:7x 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 2x 2x 3x 5x 11 = 2640

Therefore, the value for common factors is 2640.

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 = 12799858579200/(1x2640)

LCM = 12799858579200/2640

LCM = 4848431280

Thus, we can understand that the LCM of 121,690,816,440,427 is 4848431280.
