Given numbers are 161,379,748,642,743

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

The LCM of 161,379,748,642,743 is 10885804488636.

Find LCM of 161,379,748,642,743 with Prime Factorization

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

2 x 161 x 379 x 374 x 321 x 743 = 10885804488636

Therefore, the lowest common multiple of 161,379,748,642,743 is 10885804488636.

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.

161 x 379 x 748 x 642 x 743 = 21771608977272

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.

161 : 1, 7, 23, 161

379 : 1, 379

748 : 1, 2, 4, 11, 17, 22, 34, 44, 68, 187, 374, 748

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

743 : 1, 743

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 161,379,748,642,743, is 1.

Now, the common factors can be found like this.

161:7x 23

379:379

748:2x 2x 11x 17

642:2x 3x 107

743:743

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

2 = 2

Therefore, the value for common factors is 2.

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 = 21771608977272/(1x2)

LCM = 21771608977272/2

LCM = 10885804488636

Thus, we can understand that the LCM of 161,379,748,642,743 is 10885804488636.
