Find LCM of 369,620,308,781,713 with Prime Factorization
| 2 | 369, 620, 308, 781, 713 |
| 2 | 369, 310, 154, 781, 713 |
| 11 | 369, 155, 77, 781, 713 |
| 31 | 369, 155, 7, 71, 713 |
| 369, 5, 7, 71, 23 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 11 x 31 x 369 x 5 x 7 x 71 x 23 = 28767025980
Therefore, the lowest common multiple of 369,620,308,781,713 is 28767025980.
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.
369 x 620 x 308 x 781 x 713 = 39238223436720
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.
369 : 1, 3, 9, 41, 123, 369
620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620
308 : 1, 2, 4, 7, 11, 14, 22, 28, 44, 77, 154, 308
781 : 1, 11, 71, 781
713 : 1, 23, 31, 713
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 369,620,308,781,713, is 1.
Now, the common factors can be found like this.
369:3x 3x 41
620:2x 2x 5x 31
308:2x 2x 7x 11
781:11x 71
713:23x 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 11x 31 = 1364
Therefore, the value for common factors is 1364.
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 = 39238223436720/(1x1364)
LCM = 39238223436720/1364
LCM = 28767025980
Thus, we can understand that the LCM of 369,620,308,781,713 is 28767025980.
