Given numbers are 421,991,842,703
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 421,991,842,703 is 586598666.
Find LCM of 421,991,842,703 with Prime Factorization
421 | 421, 991, 842, 703 |
1, 991, 2, 703 |
Multiply the prime numbers at the bottom and the left side.
421 x 1 x 991 x 2 x 703 = 586598666
Therefore, the lowest common multiple of 421,991,842,703 is 586598666.
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 991 x 842 x 703 = 246958038386
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
991 : 1, 991
842 : 1, 2, 421, 842
703 : 1, 19, 37, 703
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 421,991,842,703, is 1.
Now, the common factors can be found like this.
421:421
991:991
842:2x 421
703:19x 37
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 = 246958038386/(1x421)
LCM = 246958038386/421
LCM = 586598666
Thus, we can understand that the LCM of 421,991,842,703 is 586598666.
