Given numbers are 442,689,393,254

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

The LCM of 442,689,393,254 is 1169215086.

Find LCM of 442,689,393,254 with Prime Factorization

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

2 x 13 x 17 x 53 x 393 x 127 = 1169215086

Therefore, the lowest common multiple of 442,689,393,254 is 1169215086.

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.

442 x 689 x 393 x 254 = 30399592236

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.

442 : 1, 2, 13, 17, 26, 34, 221, 442

689 : 1, 13, 53, 689

393 : 1, 3, 131, 393

254 : 1, 2, 127, 254

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 442,689,393,254, is 1.

Now, the common factors can be found like this.

442:2x 13x 17

689:13x 53

393:3x 131

254:2x 127

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

2x 13 = 26

Therefore, the value for common factors is 26.

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 = 30399592236/(1x26)

LCM = 30399592236/26

LCM = 1169215086

Thus, we can understand that the LCM of 442,689,393,254 is 1169215086.
