Given numbers are 637,104,254,78

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

The LCM of 637,104,254,78 is 1941576.

Find LCM of 637,104,254,78 with Prime Factorization

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

2 x 13 x 49 x 4 x 127 x 3 = 1941576

Therefore, the lowest common multiple of 637,104,254,78 is 1941576.

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.

637 x 104 x 254 x 78 = 1312505376

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.

637 : 1, 7, 13, 49, 91, 637

104 : 1, 2, 4, 8, 13, 26, 52, 104

254 : 1, 2, 127, 254

78 : 1, 2, 3, 6, 13, 26, 39, 78

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 637,104,254,78, is 1.

Now, the common factors can be found like this.

637:7x 7x 13

104:2x 2x 2x 13

254:2x 127

78:2x 3x 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 2x 13x 13 = 676

Therefore, the value for common factors is 676.

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 = 1312505376/(1x676)

LCM = 1312505376/676

LCM = 1941576

Thus, we can understand that the LCM of 637,104,254,78 is 1941576.
