Given numbers are 215,989,651,708
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 215,989,651,708 is 759730020.
Find LCM of 215,989,651,708 with Prime Factorization
| 3 | 215, 989, 651, 708 |
| 43 | 215, 989, 217, 236 |
| 5, 23, 217, 236 |
Multiply the prime numbers at the bottom and the left side.
3 x 43 x 5 x 23 x 217 x 236 = 759730020
Therefore, the lowest common multiple of 215,989,651,708 is 759730020.
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.
215 x 989 x 651 x 708 = 98005172580
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.
215 : 1, 5, 43, 215
989 : 1, 23, 43, 989
651 : 1, 3, 7, 21, 31, 93, 217, 651
708 : 1, 2, 3, 4, 6, 12, 59, 118, 177, 236, 354, 708
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 215,989,651,708, is 1.
Now, the common factors can be found like this.
215:5x 43
989:23x 43
651:3x 7x 31
708:2x 2x 3x 59
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 43 = 129
Therefore, the value for common factors is 129.
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 = 98005172580/(1x129)
LCM = 98005172580/129
LCM = 759730020
Thus, we can understand that the LCM of 215,989,651,708 is 759730020.
