Given numbers are 681,154,253,682

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

The LCM of 681,154,253,682 is 74775162.

Find LCM of 681,154,253,682 with Prime Factorization

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

2 x 11 x 681 x 7 x 23 x 31 = 74775162

Therefore, the lowest common multiple of 681,154,253,682 is 74775162.

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.

681 x 154 x 253 x 682 = 18095589204

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.

681 : 1, 3, 227, 681

154 : 1, 2, 7, 11, 14, 22, 77, 154

253 : 1, 11, 23, 253

682 : 1, 2, 11, 22, 31, 62, 341, 682

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 681,154,253,682, is 1.

Now, the common factors can be found like this.

681:3x 227

154:2x 7x 11

253:11x 23

682:2x 11x 31

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

2x 11x 11 = 242

Therefore, the value for common factors is 242.

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 = 18095589204/(1x242)

LCM = 18095589204/242

LCM = 74775162

Thus, we can understand that the LCM of 681,154,253,682 is 74775162.
