Given numbers are 778,436,372,989
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 778,436,372,989 is 15599667108.
Find LCM of 778,436,372,989 with Prime Factorization
| 2 | 778, 436, 372, 989 |
| 2 | 389, 218, 186, 989 |
| 389, 109, 93, 989 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 389 x 109 x 93 x 989 = 15599667108
Therefore, the lowest common multiple of 778,436,372,989 is 15599667108.
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.
778 x 436 x 372 x 989 = 124797336864
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.
778 : 1, 2, 389, 778
436 : 1, 2, 4, 109, 218, 436
372 : 1, 2, 3, 4, 6, 12, 31, 62, 93, 124, 186, 372
989 : 1, 23, 43, 989
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 778,436,372,989, is 1.
Now, the common factors can be found like this.
778:2x 389
436:2x 2x 109
372:2x 2x 3x 31
989:23x 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 2 = 8
Therefore, the value for common factors is 8.
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 = 124797336864/(1x8)
LCM = 124797336864/8
LCM = 15599667108
Thus, we can understand that the LCM of 778,436,372,989 is 15599667108.
