Find LCM of 920,444,262,210,989 with Prime Factorization
| 2 | 920, 444, 262, 210, 989 |
| 2 | 460, 222, 131, 105, 989 |
| 3 | 230, 111, 131, 105, 989 |
| 5 | 230, 37, 131, 35, 989 |
| 23 | 46, 37, 131, 7, 989 |
| 2, 37, 131, 7, 43 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 23 x 2 x 37 x 131 x 7 x 43 = 4026693720
Therefore, the lowest common multiple of 920,444,262,210,989 is 4026693720.
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.
920 x 444 x 262 x 210 x 989 = 22227349334400
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.
920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920
444 : 1, 2, 3, 4, 6, 12, 37, 74, 111, 148, 222, 444
262 : 1, 2, 131, 262
210 : 1, 2, 3, 5, 6, 7, 10, 14, 15, 21, 30, 35, 42, 70, 105, 210
989 : 1, 23, 43, 989
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 920,444,262,210,989, is 1.
Now, the common factors can be found like this.
920:2x 2x 2x 5x 23
444:2x 2x 3x 37
262:2x 131
210:2x 3x 5x 7
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 2x 2x 3x 5x 23 = 5520
Therefore, the value for common factors is 5520.
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 = 22227349334400/(1x5520)
LCM = 22227349334400/5520
LCM = 4026693720
Thus, we can understand that the LCM of 920,444,262,210,989 is 4026693720.
