Given numbers are 620,445,103,435

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

The LCM of 620,445,103,435 is 494467980.

Find LCM of 620,445,103,435 with Prime Factorization

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

5 x 124 x 89 x 103 x 87 = 494467980

Therefore, the lowest common multiple of 620,445,103,435 is 494467980.

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 445 x 103 x 435 = 12361699500

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

445 : 1, 5, 89, 445

103 : 1, 103

435 : 1, 3, 5, 15, 29, 87, 145, 435

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 620,445,103,435, is 1.

Now, the common factors can be found like this.

620:2x 2x 5x 31

445:5x 89

103:103

435:3x 5x 29

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

5x 5 = 25

Therefore, the value for common factors is 25.

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 = 12361699500/(1x25)

LCM = 12361699500/25

LCM = 494467980

Thus, we can understand that the LCM of 620,445,103,435 is 494467980.
