Find LCM of 890,680,493,744 with Prime Factorization
| 2 | 890, 680, 493, 744 |
| 2 | 445, 340, 493, 372 |
| 2 | 445, 170, 493, 186 |
| 5 | 445, 85, 493, 93 |
| 17 | 89, 17, 493, 93 |
| 89, 1, 29, 93 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 5 x 17 x 89 x 1 x 29 x 93 = 163222440
Therefore, the lowest common multiple of 890,680,493,744 is 163222440.
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.
890 x 680 x 493 x 744 = 221982518400
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.
890 : 1, 2, 5, 10, 89, 178, 445, 890
680 : 1, 2, 4, 5, 8, 10, 17, 20, 34, 40, 68, 85, 136, 170, 340, 680
493 : 1, 17, 29, 493
744 : 1, 2, 3, 4, 6, 8, 12, 24, 31, 62, 93, 124, 186, 248, 372, 744
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 890,680,493,744, is 1.
Now, the common factors can be found like this.
890:2x 5x 89
680:2x 2x 2x 5x 17
493:17x 29
744:2x 2x 2x 3x 31
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 5x 17 = 1360
Therefore, the value for common factors is 1360.
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 = 221982518400/(1x1360)
LCM = 221982518400/1360
LCM = 163222440
Thus, we can understand that the LCM of 890,680,493,744 is 163222440.
