Given numbers are 721,472,212,169

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

The LCM of 721,472,212,169 is 3048174584.

Find LCM of 721,472,212,169 with Prime Factorization

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

2 x 2 x 721 x 118 x 53 x 169 = 3048174584

Therefore, the lowest common multiple of 721,472,212,169 is 3048174584.

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.

721 x 472 x 212 x 169 = 12192698336

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.

721 : 1, 7, 103, 721

472 : 1, 2, 4, 8, 59, 118, 236, 472

212 : 1, 2, 4, 53, 106, 212

169 : 1, 13, 169

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 721,472,212,169, is 1.

Now, the common factors can be found like this.

721:7x 103

472:2x 2x 2x 59

212:2x 2x 53

169:13x 13

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 12192698336/(1x4)

LCM = 12192698336/4

LCM = 3048174584

Thus, we can understand that the LCM of 721,472,212,169 is 3048174584.
