Given numbers are 620,730,253,223

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

The LCM of 620,730,253,223 is 2553523940.

Find LCM of 620,730,253,223 with Prime Factorization

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

2 x 5 x 62 x 73 x 253 x 223 = 2553523940

Therefore, the lowest common multiple of 620,730,253,223 is 2553523940.

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.

620 x 730 x 253 x 223 = 25535239400

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.

620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620

730 : 1, 2, 5, 10, 73, 146, 365, 730

253 : 1, 11, 23, 253

223 : 1, 223

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 620,730,253,223, is 1.

Now, the common factors can be found like this.

620:2x 2x 5x 31

730:2x 5x 73

253:11x 23

223:223

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

2x 5 = 10

Therefore, the value for common factors is 10.

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 = 25535239400/(1x10)

LCM = 25535239400/10

LCM = 2553523940

Thus, we can understand that the LCM of 620,730,253,223 is 2553523940.
