Given numbers are 318,710,721,850,221
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 318,710,721,850,221 is 89940027450.
Find LCM of 318,710,721,850,221 with Prime Factorization
| 2 | 318, 710, 721, 850, 221 |
| 5 | 159, 355, 721, 425, 221 |
| 17 | 159, 71, 721, 85, 221 |
| 159, 71, 721, 5, 13 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 17 x 159 x 71 x 721 x 5 x 13 = 89940027450
Therefore, the lowest common multiple of 318,710,721,850,221 is 89940027450.
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.
318 x 710 x 721 x 850 x 221 = 30579609333000
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.
318 : 1, 2, 3, 6, 53, 106, 159, 318
710 : 1, 2, 5, 10, 71, 142, 355, 710
721 : 1, 7, 103, 721
850 : 1, 2, 5, 10, 17, 25, 34, 50, 85, 170, 425, 850
221 : 1, 13, 17, 221
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 318,710,721,850,221, is 1.
Now, the common factors can be found like this.
318:2x 3x 53
710:2x 5x 71
721:7x 103
850:2x 5x 5x 17
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 5x 17 = 340
Therefore, the value for common factors is 340.
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 = 30579609333000/(1x340)
LCM = 30579609333000/340
LCM = 89940027450
Thus, we can understand that the LCM of 318,710,721,850,221 is 89940027450.
