Given numbers are 903,521,519,168,420

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

The LCM of 903,521,519,168,420 is 3255603960.

Find LCM of 903,521,519,168,420 with Prime Factorization

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

2 x 2 x 3 x 7 x 43 x 521 x 173 x 2 x 5 = 3255603960

Therefore, the lowest common multiple of 903,521,519,168,420 is 3255603960.

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.

903 x 521 x 519 x 168 x 420 = 17228656156320

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.

903 : 1, 3, 7, 21, 43, 129, 301, 903

521 : 1, 521

519 : 1, 3, 173, 519

168 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 21, 24, 28, 42, 56, 84, 168

420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 903,521,519,168,420, is 1.

Now, the common factors can be found like this.

903:3x 7x 43

521:521

519:3x 173

168:2x 2x 2x 3x 7

420:2x 2x 3x 5x 7

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 3x 3x 3x 7x 7 = 5292

Therefore, the value for common factors is 5292.

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 = 17228656156320/(1x5292)

LCM = 17228656156320/5292

LCM = 3255603960

Thus, we can understand that the LCM of 903,521,519,168,420 is 3255603960.
