Given numbers are 421,578,178,565,710

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

The LCM of 421,578,178,565,710 is 868773844430.

Find LCM of 421,578,178,565,710 with Prime Factorization

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

2 x 5 x 421 x 289 x 89 x 113 x 71 = 868773844430

Therefore, the lowest common multiple of 421,578,178,565,710 is 868773844430.

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.

421 x 578 x 178 x 565 x 710 = 17375476888600

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.

421 : 1, 421

578 : 1, 2, 17, 34, 289, 578

178 : 1, 2, 89, 178

565 : 1, 5, 113, 565

710 : 1, 2, 5, 10, 71, 142, 355, 710

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 421,578,178,565,710, is 1.

Now, the common factors can be found like this.

421:421

578:2x 17x 17

178:2x 89

565:5x 113

710:2x 5x 71

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 5 = 20

Therefore, the value for common factors is 20.

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 = 17375476888600/(1x20)

LCM = 17375476888600/20

LCM = 868773844430

Thus, we can understand that the LCM of 421,578,178,565,710 is 868773844430.
