Find LCM of 650,222,520,364,728 with Prime Factorization
| 2 | 650, 222, 520, 364, 728 |
| 2 | 325, 111, 260, 182, 364 |
| 2 | 325, 111, 130, 91, 182 |
| 5 | 325, 111, 65, 91, 91 |
| 7 | 13, 111, 65, 91, 91 |
| 13 | 13, 111, 65, 13, 13 |
| 1, 111, 5, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 5 x 7 x 13 x 1 x 111 x 5 x 1 x 1 = 2020200
Therefore, the lowest common multiple of 650,222,520,364,728 is 2020200.
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.
650 x 222 x 520 x 364 x 728 = 19883939712000
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.
650 : 1, 2, 5, 10, 13, 25, 26, 50, 65, 130, 325, 650
222 : 1, 2, 3, 6, 37, 74, 111, 222
520 : 1, 2, 4, 5, 8, 10, 13, 20, 26, 40, 52, 65, 104, 130, 260, 520
364 : 1, 2, 4, 7, 13, 14, 26, 28, 52, 91, 182, 364
728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 650,222,520,364,728, is 2.
Now, the common factors can be found like this.
650:2x 5x 5x 13
222:2x 3x 37
520:2x 2x 2x 5x 13
364:2x 2x 7x 13
728:2x 2x 2x 7x 13
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 2x 2x 5x 7x 13x 13x 13 = 4921280
Therefore, the value for common factors is 4921280.
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 = 19883939712000/(2x4921280)
LCM = 19883939712000/9842560
LCM = 2020200
Thus, we can understand that the LCM of 650,222,520,364,728 is 2020200.
