Find LCM of 774,862,720,376,690 with Prime Factorization
| 2 | 774, 862, 720, 376, 690 |
| 2 | 387, 431, 360, 188, 345 |
| 2 | 387, 431, 180, 94, 345 |
| 3 | 387, 431, 90, 47, 345 |
| 3 | 129, 431, 30, 47, 115 |
| 5 | 43, 431, 10, 47, 115 |
| 43, 431, 2, 47, 23 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 3 x 5 x 43 x 431 x 2 x 47 x 23 = 14424604560
Therefore, the lowest common multiple of 774,862,720,376,690 is 14424604560.
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.
774 x 862 x 720 x 376 x 690 = 124628583398400
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.
774 : 1, 2, 3, 6, 9, 18, 43, 86, 129, 258, 387, 774
862 : 1, 2, 431, 862
720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720
376 : 1, 2, 4, 8, 47, 94, 188, 376
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 774,862,720,376,690, is 2.
Now, the common factors can be found like this.
774:2x 3x 3x 43
862:2x 431
720:2x 2x 2x 2x 3x 3x 5
376:2x 2x 2x 47
690:2x 3x 5x 23
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 3x 3x 3x 5 = 4320
Therefore, the value for common factors is 4320.
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 = 124628583398400/(2x4320)
LCM = 124628583398400/8640
LCM = 14424604560
Thus, we can understand that the LCM of 774,862,720,376,690 is 14424604560.
