Given numbers are 254,420,454,695

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

The LCM of 254,420,454,695 is 1683037020.

Find LCM of 254,420,454,695 with Prime Factorization

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

2 x 5 x 127 x 42 x 227 x 139 = 1683037020

Therefore, the lowest common multiple of 254,420,454,695 is 1683037020.

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.

254 x 420 x 454 x 695 = 33660740400

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.

254 : 1, 2, 127, 254

420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420

454 : 1, 2, 227, 454

695 : 1, 5, 139, 695

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 254,420,454,695, is 1.

Now, the common factors can be found like this.

254:2x 127

420:2x 2x 3x 5x 7

454:2x 227

695:5x 139

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 5 = 20

Therefore, the value for common factors is 20.

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 = 33660740400/(1x20)

LCM = 33660740400/20

LCM = 1683037020

Thus, we can understand that the LCM of 254,420,454,695 is 1683037020.
