Given numbers are 842,315,421,803

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

The LCM of 842,315,421,803 is 212979690.

Find LCM of 842,315,421,803 with Prime Factorization

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

421 x 2 x 315 x 1 x 803 = 212979690

Therefore, the lowest common multiple of 842,315,421,803 is 212979690.

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.

842 x 315 x 421 x 803 = 89664449490

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.

842 : 1, 2, 421, 842

315 : 1, 3, 5, 7, 9, 15, 21, 35, 45, 63, 105, 315

421 : 1, 421

803 : 1, 11, 73, 803

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 842,315,421,803, is 1.

Now, the common factors can be found like this.

842:2x 421

315:3x 3x 5x 7

421:421

803:11x 73

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

421 = 421

Therefore, the value for common factors is 421.

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 = 89664449490/(1x421)

LCM = 89664449490/421

LCM = 212979690

Thus, we can understand that the LCM of 842,315,421,803 is 212979690.
