Given numbers are 688,421,958,622,994

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

The LCM of 688,421,958,622,994 is 21444840737264.

Find LCM of 688,421,958,622,994 with Prime Factorization

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

2 x 344 x 421 x 479 x 311 x 497 = 21444840737264

Therefore, the lowest common multiple of 688,421,958,622,994 is 21444840737264.

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.

688 x 421 x 958 x 622 x 994 = 171558725898112

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.

688 : 1, 2, 4, 8, 16, 43, 86, 172, 344, 688

421 : 1, 421

958 : 1, 2, 479, 958

622 : 1, 2, 311, 622

994 : 1, 2, 7, 14, 71, 142, 497, 994

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 688,421,958,622,994, is 1.

Now, the common factors can be found like this.

688:2x 2x 2x 2x 43

421:421

958:2x 479

622:2x 311

994:2x 7x 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 2 = 8

Therefore, the value for common factors is 8.

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 = 171558725898112/(1x8)

LCM = 171558725898112/8

LCM = 21444840737264

Thus, we can understand that the LCM of 688,421,958,622,994 is 21444840737264.
