Given numbers are 902,470,421,428

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

The LCM of 902,470,421,428 is 19097225180.

Find LCM of 902,470,421,428 with Prime Factorization

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

2 x 451 x 235 x 421 x 214 = 19097225180

Therefore, the lowest common multiple of 902,470,421,428 is 19097225180.

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.

902 x 470 x 421 x 428 = 76388900720

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.

902 : 1, 2, 11, 22, 41, 82, 451, 902

470 : 1, 2, 5, 10, 47, 94, 235, 470

421 : 1, 421

428 : 1, 2, 4, 107, 214, 428

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 902,470,421,428, is 1.

Now, the common factors can be found like this.

902:2x 11x 41

470:2x 5x 47

421:421

428:2x 2x 107

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 76388900720/(1x4)

LCM = 76388900720/4

LCM = 19097225180

Thus, we can understand that the LCM of 902,470,421,428 is 19097225180.
