Given numbers are 2,989,688,942
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 2,989,688,942 is 7453104.
Find LCM of 2,989,688,942 with Prime Factorization
| 2 | 2, 989, 688, 942 |
| 43 | 1, 989, 344, 471 |
| 1, 23, 8, 471 |
Multiply the prime numbers at the bottom and the left side.
2 x 43 x 1 x 23 x 8 x 471 = 7453104
Therefore, the lowest common multiple of 2,989,688,942 is 7453104.
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.
2 x 989 x 688 x 942 = 1281933888
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.
2 : 1, 2
989 : 1, 23, 43, 989
688 : 1, 2, 4, 8, 16, 43, 86, 172, 344, 688
942 : 1, 2, 3, 6, 157, 314, 471, 942
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 2,989,688,942, is 1.
Now, the common factors can be found like this.
2:2
989:23x 43
688:2x 2x 2x 2x 43
942:2x 3x 157
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 43 = 172
Therefore, the value for common factors is 172.
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 = 1281933888/(1x172)
LCM = 1281933888/172
LCM = 7453104
Thus, we can understand that the LCM of 2,989,688,942 is 7453104.
