Given numbers are 620,720,425,430,148

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

The LCM of 620,720,425,430,148 is 3018445200.

Find LCM of 620,720,425,430,148 with Prime Factorization

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

2 x 2 x 5 x 31 x 36 x 85 x 43 x 37 = 3018445200

Therefore, the lowest common multiple of 620,720,425,430,148 is 3018445200.

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 720 x 425 x 430 x 148 = 12073780800000

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

720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720

425 : 1, 5, 17, 25, 85, 425

430 : 1, 2, 5, 10, 43, 86, 215, 430

148 : 1, 2, 4, 37, 74, 148

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 620,720,425,430,148, is 1.

Now, the common factors can be found like this.

620:2x 2x 5x 31

720:2x 2x 2x 2x 3x 3x 5

425:5x 5x 17

430:2x 5x 43

148:2x 2x 37

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 2x 2x 2x 5x 5x 5 = 4000

Therefore, the value for common factors is 4000.

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 = 12073780800000/(1x4000)

LCM = 12073780800000/4000

LCM = 3018445200

Thus, we can understand that the LCM of 620,720,425,430,148 is 3018445200.
