Find LCM of 781,109,480,611,496 with Prime Factorization
| 2 | 781, 109, 480, 611, 496 |
| 2 | 781, 109, 240, 611, 248 |
| 2 | 781, 109, 120, 611, 124 |
| 2 | 781, 109, 60, 611, 62 |
| 781, 109, 30, 611, 31 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 781 x 109 x 30 x 611 x 31 = 773965626720
Therefore, the lowest common multiple of 781,109,480,611,496 is 773965626720.
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.
781 x 109 x 480 x 611 x 496 = 12383450027520
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.
781 : 1, 11, 71, 781
109 : 1, 109
480 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 32, 40, 48, 60, 80, 96, 120, 160, 240, 480
611 : 1, 13, 47, 611
496 : 1, 2, 4, 8, 16, 31, 62, 124, 248, 496
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 781,109,480,611,496, is 1.
Now, the common factors can be found like this.
781:11x 71
109:109
480:2x 2x 2x 2x 2x 3x 5
611:13x 47
496:2x 2x 2x 2x 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 2 = 16
Therefore, the value for common factors is 16.
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 = 12383450027520/(1x16)
LCM = 12383450027520/16
LCM = 773965626720
Thus, we can understand that the LCM of 781,109,480,611,496 is 773965626720.
