Given numbers are 253,875,621,781

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

The LCM of 253,875,621,781 is 424375875.

Find LCM of 253,875,621,781 with Prime Factorization

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

11 x 23 x 1 x 875 x 27 x 71 = 424375875

Therefore, the lowest common multiple of 253,875,621,781 is 424375875.

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.

253 x 875 x 621 x 781 = 107367096375

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.

253 : 1, 11, 23, 253

875 : 1, 5, 7, 25, 35, 125, 175, 875

621 : 1, 3, 9, 23, 27, 69, 207, 621

781 : 1, 11, 71, 781

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 253,875,621,781, is 1.

Now, the common factors can be found like this.

253:11x 23

875:5x 5x 5x 7

621:3x 3x 3x 23

781:11x 71

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

11x 23 = 253

Therefore, the value for common factors is 253.

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 = 107367096375/(1x253)

LCM = 107367096375/253

LCM = 424375875

Thus, we can understand that the LCM of 253,875,621,781 is 424375875.
