Given numbers are 906,392,973,989,489
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 906,392,973,989,489 is 3979082698248.
Find LCM of 906,392,973,989,489 with Prime Factorization
| 2 | 906, 392, 973, 989, 489 |
| 3 | 453, 196, 973, 989, 489 |
| 7 | 151, 196, 973, 989, 163 |
| 151, 28, 139, 989, 163 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 151 x 28 x 139 x 989 x 163 = 3979082698248
Therefore, the lowest common multiple of 906,392,973,989,489 is 3979082698248.
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.
906 x 392 x 973 x 989 x 489 = 167121473326416
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.
906 : 1, 2, 3, 6, 151, 302, 453, 906
392 : 1, 2, 4, 7, 8, 14, 28, 49, 56, 98, 196, 392
973 : 1, 7, 139, 973
989 : 1, 23, 43, 989
489 : 1, 3, 163, 489
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 906,392,973,989,489, is 1.
Now, the common factors can be found like this.
906:2x 3x 151
392:2x 2x 2x 7x 7
973:7x 139
989:23x 43
489:3x 163
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 7 = 42
Therefore, the value for common factors is 42.
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 = 167121473326416/(1x42)
LCM = 167121473326416/42
LCM = 3979082698248
Thus, we can understand that the LCM of 906,392,973,989,489 is 3979082698248.
