Given numbers are 736,989,915,865
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 736,989,915,865 is 5009720160.
Find LCM of 736,989,915,865 with Prime Factorization
| 5 | 736, 989, 915, 865 |
| 23 | 736, 989, 183, 173 |
| 32, 43, 183, 173 |
Multiply the prime numbers at the bottom and the left side.
5 x 23 x 32 x 43 x 183 x 173 = 5009720160
Therefore, the lowest common multiple of 736,989,915,865 is 5009720160.
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.
736 x 989 x 915 x 865 = 576117818400
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.
736 : 1, 2, 4, 8, 16, 23, 32, 46, 92, 184, 368, 736
989 : 1, 23, 43, 989
915 : 1, 3, 5, 15, 61, 183, 305, 915
865 : 1, 5, 173, 865
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 736,989,915,865, is 1.
Now, the common factors can be found like this.
736:2x 2x 2x 2x 2x 23
989:23x 43
915:3x 5x 61
865:5x 173
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 23 = 115
Therefore, the value for common factors is 115.
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 = 576117818400/(1x115)
LCM = 576117818400/115
LCM = 5009720160
Thus, we can understand that the LCM of 736,989,915,865 is 5009720160.
