The LCM of 199,782,245,221,294 is 1486929990.
Find LCM of 199,782,245,221,294 with Prime Factorization
| 2 | 199, 782, 245, 221, 294 |
| 7 | 199, 391, 245, 221, 147 |
| 7 | 199, 391, 35, 221, 21 |
| 17 | 199, 391, 5, 221, 3 |
| 199, 23, 5, 13, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 7 x 17 x 199 x 23 x 5 x 13 x 3 = 1486929990
Therefore, the lowest common multiple of 199,782,245,221,294 is 1486929990.
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.
199 x 782 x 245 x 221 x 294 = 2477225363340
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.
199 : 1, 199
782 : 1, 2, 17, 23, 34, 46, 391, 782
245 : 1, 5, 7, 35, 49, 245
221 : 1, 13, 17, 221
294 : 1, 2, 3, 6, 7, 14, 21, 42, 49, 98, 147, 294
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 199,782,245,221,294, is 1.
Now, the common factors can be found like this.
199:199
782:2x 17x 23
245:5x 7x 7
221:13x 17
294:2x 3x 7x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 7x 7x 17 = 1666
Therefore, the value for common factors is 1666.
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 = 2477225363340/(1x1666)
LCM = 2477225363340/1666
LCM = 1486929990
Thus, we can understand that the LCM of 199,782,245,221,294 is 1486929990.
