Given numbers are 253,611,390

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

The LCM of 253,611,390 is 4637490.

Find LCM of 253,611,390 with Prime Factorization

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

13 x 253 x 47 x 30 = 4637490

Therefore, the lowest common multiple of 253,611,390 is 4637490.

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 611 x 390 = 60287370

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

611 : 1, 13, 47, 611

390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 253,611,390, is 1.

Now, the common factors can be found like this.

253:11x 23

611:13x 47

390:2x 3x 5x 13

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

13 = 13

Therefore, the value for common factors is 13.

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 = 60287370/(1x13)

LCM = 60287370/13

LCM = 4637490

Thus, we can understand that the LCM of 253,611,390 is 4637490.

Here are some samples of LCM of two or more Numbers calculations.
