Given numbers are 102,221,281,629,840

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

The LCM of 102,221,281,629,840 is 1930099080.

Find LCM of 102,221,281,629,840 with Prime Factorization

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

2 x 3 x 17 x 1 x 13 x 281 x 37 x 140 = 1930099080

Therefore, the lowest common multiple of 102,221,281,629,840 is 1930099080.

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.

102 x 221 x 281 x 629 x 840 = 3346791804720

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.

102 : 1, 2, 3, 6, 17, 34, 51, 102

221 : 1, 13, 17, 221

281 : 1, 281

629 : 1, 17, 37, 629

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 102,221,281,629,840, is 1.

Now, the common factors can be found like this.

102:2x 3x 17

221:13x 17

281:281

629:17x 37

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

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2x 3x 17x 17 = 1734

Therefore, the value for common factors is 1734.

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 = 3346791804720/(1x1734)

LCM = 3346791804720/1734

LCM = 1930099080

Thus, we can understand that the LCM of 102,221,281,629,840 is 1930099080.
