Given numbers are 556,158,988,817
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 556,158,988,817 is 466516804.
Find LCM of 556,158,988,817 with Prime Factorization
2 | 556, 158, 988, 817 |
2 | 278, 79, 494, 817 |
19 | 139, 79, 247, 817 |
139, 79, 13, 43 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 19 x 139 x 79 x 13 x 43 = 466516804
Therefore, the lowest common multiple of 556,158,988,817 is 466516804.
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.
556 x 158 x 988 x 817 = 70910554208
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.
556 : 1, 2, 4, 139, 278, 556
158 : 1, 2, 79, 158
988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988
817 : 1, 19, 43, 817
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 556,158,988,817, is 1.
Now, the common factors can be found like this.
556:2x 2x 139
158:2x 79
988:2x 2x 13x 19
817:19x 43
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 19 = 152
Therefore, the value for common factors is 152.
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 = 70910554208/(1x152)
LCM = 70910554208/152
LCM = 466516804
Thus, we can understand that the LCM of 556,158,988,817 is 466516804.
