Given numbers are 556,901,695,986
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 556,901,695,986 is 72638620.
Find LCM of 556,901,695,986 with Prime Factorization
| 2 | 556, 901, 695, 986 |
| 17 | 278, 901, 695, 493 |
| 139 | 278, 53, 695, 29 |
| 2, 53, 5, 29 |
Multiply the prime numbers at the bottom and the left side.
2 x 17 x 139 x 2 x 53 x 5 x 29 = 72638620
Therefore, the lowest common multiple of 556,901,695,986 is 72638620.
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 901 x 695 x 986 = 343290118120
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
901 : 1, 17, 53, 901
695 : 1, 5, 139, 695
986 : 1, 2, 17, 29, 34, 58, 493, 986
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 556,901,695,986, is 1.
Now, the common factors can be found like this.
556:2x 2x 139
901:17x 53
695:5x 139
986:2x 17x 29
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 17x 139 = 4726
Therefore, the value for common factors is 4726.
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 = 343290118120/(1x4726)
LCM = 343290118120/4726
LCM = 72638620
Thus, we can understand that the LCM of 556,901,695,986 is 72638620.
