Given numbers are 624,407,222,161

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

The LCM of 624,407,222,161 is 40888848.

Find LCM of 624,407,222,161 with Prime Factorization

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

2 x 3 x 37 x 104 x 11 x 1 x 161 = 40888848

Therefore, the lowest common multiple of 624,407,222,161 is 40888848.

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.

624 x 407 x 222 x 161 = 9077324256

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.

624 : 1, 2, 3, 4, 6, 8, 12, 13, 16, 24, 26, 39, 48, 52, 78, 104, 156, 208, 312, 624

407 : 1, 11, 37, 407

222 : 1, 2, 3, 6, 37, 74, 111, 222

161 : 1, 7, 23, 161

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 624,407,222,161, is 1.

Now, the common factors can be found like this.

624:2x 2x 2x 2x 3x 13

407:11x 37

222:2x 3x 37

161:7x 23

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 37 = 222

Therefore, the value for common factors is 222.

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 = 9077324256/(1x222)

LCM = 9077324256/222

LCM = 40888848

Thus, we can understand that the LCM of 624,407,222,161 is 40888848.
