Given numbers are 980,356,466,445,221
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 980,356,466,445,221 is 4491219460.
Find LCM of 980,356,466,445,221 with Prime Factorization
| 2 | 980, 356, 466, 445, 221 |
| 2 | 490, 178, 233, 445, 221 |
| 5 | 245, 89, 233, 445, 221 |
| 89 | 49, 89, 233, 89, 221 |
| 49, 1, 233, 1, 221 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 89 x 49 x 1 x 233 x 1 x 221 = 4491219460
Therefore, the lowest common multiple of 980,356,466,445,221 is 4491219460.
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.
980 x 356 x 466 x 445 x 221 = 15988741277600
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.
980 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 49, 70, 98, 140, 196, 245, 490, 980
356 : 1, 2, 4, 89, 178, 356
466 : 1, 2, 233, 466
445 : 1, 5, 89, 445
221 : 1, 13, 17, 221
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 980,356,466,445,221, is 1.
Now, the common factors can be found like this.
980:2x 2x 5x 7x 7
356:2x 2x 89
466:2x 233
445:5x 89
221:13x 17
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 5x 89 = 3560
Therefore, the value for common factors is 3560.
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 = 15988741277600/(1x3560)
LCM = 15988741277600/3560
LCM = 4491219460
Thus, we can understand that the LCM of 980,356,466,445,221 is 4491219460.
