Given numbers are 862,345,622,118,642

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

The LCM of 862,345,622,118,642 is 583878574770.

Find LCM of 862,345,622,118,642 with Prime Factorization

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

2 x 3 x 431 x 115 x 311 x 59 x 107 = 583878574770

Therefore, the lowest common multiple of 862,345,622,118,642 is 583878574770.

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.

862 x 345 x 622 x 118 x 642 = 14013085794480

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.

862 : 1, 2, 431, 862

345 : 1, 3, 5, 15, 23, 69, 115, 345

622 : 1, 2, 311, 622

118 : 1, 2, 59, 118

642 : 1, 2, 3, 6, 107, 214, 321, 642

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 862,345,622,118,642, is 1.

Now, the common factors can be found like this.

862:2x 431

345:3x 5x 23

622:2x 311

118:2x 59

642:2x 3x 107

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 3 = 24

Therefore, the value for common factors is 24.

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 = 14013085794480/(1x24)

LCM = 14013085794480/24

LCM = 583878574770

Thus, we can understand that the LCM of 862,345,622,118,642 is 583878574770.
