Given numbers are 312,991,968,473
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 312,991,968,473 is 1608725976.
Find LCM of 312,991,968,473 with Prime Factorization
| 2 | 312, 991, 968, 473 |
| 2 | 156, 991, 484, 473 |
| 2 | 78, 991, 242, 473 |
| 11 | 39, 991, 121, 473 |
| 39, 991, 11, 43 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 11 x 39 x 991 x 11 x 43 = 1608725976
Therefore, the lowest common multiple of 312,991,968,473 is 1608725976.
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.
312 x 991 x 968 x 473 = 141567885888
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.
312 : 1, 2, 3, 4, 6, 8, 12, 13, 24, 26, 39, 52, 78, 104, 156, 312
991 : 1, 991
968 : 1, 2, 4, 8, 11, 22, 44, 88, 121, 242, 484, 968
473 : 1, 11, 43, 473
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 312,991,968,473, is 1.
Now, the common factors can be found like this.
312:2x 2x 2x 3x 13
991:991
968:2x 2x 2x 11x 11
473:11x 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 11 = 88
Therefore, the value for common factors is 88.
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 = 141567885888/(1x88)
LCM = 141567885888/88
LCM = 1608725976
Thus, we can understand that the LCM of 312,991,968,473 is 1608725976.
