Given numbers are 251,672,192,161

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

The LCM of 251,672,192,161 is 7758912.

Find LCM of 251,672,192,161 with Prime Factorization

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

2 x 2 x 2 x 2 x 2 x 3 x 7 x 251 x 1 x 2 x 23 = 7758912

Therefore, the lowest common multiple of 251,672,192,161 is 7758912.

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.

251 x 672 x 192 x 161 = 5213988864

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.

251 : 1, 251

672 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 16, 21, 24, 28, 32, 42, 48, 56, 84, 96, 112, 168, 224, 336, 672

192 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 192

161 : 1, 7, 23, 161

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 251,672,192,161, is 1.

Now, the common factors can be found like this.

251:251

672:2x 2x 2x 2x 2x 3x 7

192:2x 2x 2x 2x 2x 2x 3

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 2x 2x 2x 2x 3x 7 = 672

Therefore, the value for common factors is 672.

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 = 5213988864/(1x672)

LCM = 5213988864/672

LCM = 7758912

Thus, we can understand that the LCM of 251,672,192,161 is 7758912.
