Given numbers are 649,323,874,421

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

The LCM of 649,323,874,421 is 4059636482.

Find LCM of 649,323,874,421 with Prime Factorization

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

19 x 649 x 17 x 46 x 421 = 4059636482

Therefore, the lowest common multiple of 649,323,874,421 is 4059636482.

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.

649 x 323 x 874 x 421 = 77133093158

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.

649 : 1, 11, 59, 649

323 : 1, 17, 19, 323

874 : 1, 2, 19, 23, 38, 46, 437, 874

421 : 1, 421

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 649,323,874,421, is 1.

Now, the common factors can be found like this.

649:11x 59

323:17x 19

874:2x 19x 23

421:421

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

19 = 19

Therefore, the value for common factors is 19.

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 = 77133093158/(1x19)

LCM = 77133093158/19

LCM = 4059636482

Thus, we can understand that the LCM of 649,323,874,421 is 4059636482.
