Given numbers are 610,340,312,221
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 610,340,312,221 is 1617720.
Find LCM of 610,340,312,221 with Prime Factorization
| 2 | 610, 340, 312, 221 |
| 2 | 305, 170, 156, 221 |
| 5 | 305, 85, 78, 221 |
| 13 | 61, 17, 78, 221 |
| 17 | 61, 17, 6, 17 |
| 61, 1, 6, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 13 x 17 x 61 x 1 x 6 x 1 = 1617720
Therefore, the lowest common multiple of 610,340,312,221 is 1617720.
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.
610 x 340 x 312 x 221 = 14300644800
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.
610 : 1, 2, 5, 10, 61, 122, 305, 610
340 : 1, 2, 4, 5, 10, 17, 20, 34, 68, 85, 170, 340
312 : 1, 2, 3, 4, 6, 8, 12, 13, 24, 26, 39, 52, 78, 104, 156, 312
221 : 1, 13, 17, 221
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 610,340,312,221, is 1.
Now, the common factors can be found like this.
610:2x 5x 61
340:2x 2x 5x 17
312:2x 2x 2x 3x 13
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 13x 17 = 8840
Therefore, the value for common factors is 8840.
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 = 14300644800/(1x8840)
LCM = 14300644800/8840
LCM = 1617720
Thus, we can understand that the LCM of 610,340,312,221 is 1617720.
