Given numbers are 598,402,178,816,420

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

The LCM of 598,402,178,816,420 is 50920680720.

Find LCM of 598,402,178,816,420 with Prime Factorization

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

2 x 2 x 3 x 299 x 67 x 89 x 68 x 35 = 50920680720

Therefore, the lowest common multiple of 598,402,178,816,420 is 50920680720.

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.

598 x 402 x 178 x 816 x 420 = 14665156047360

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.

598 : 1, 2, 13, 23, 26, 46, 299, 598

402 : 1, 2, 3, 6, 67, 134, 201, 402

178 : 1, 2, 89, 178

816 : 1, 2, 3, 4, 6, 8, 12, 16, 17, 24, 34, 48, 51, 68, 102, 136, 204, 272, 408, 816

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

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 598,402,178,816,420, is 2.

Now, the common factors can be found like this.

598:2x 13x 23

402:2x 3x 67

178:2x 89

816:2x 2x 2x 2x 3x 17

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 2x 2x 3x 3 = 144

Therefore, the value for common factors is 144.

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 = 14665156047360/(2x144)

LCM = 14665156047360/288

LCM = 50920680720

Thus, we can understand that the LCM of 598,402,178,816,420 is 50920680720.
