Find LCM of 684,421,960,697,310 with Prime Factorization
| 2 | 684, 421, 960, 697, 310 |
| 2 | 342, 421, 480, 697, 155 |
| 3 | 171, 421, 240, 697, 155 |
| 5 | 57, 421, 80, 697, 155 |
| 57, 421, 16, 697, 31 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 57 x 421 x 16 x 697 x 31 = 497763051840
Therefore, the lowest common multiple of 684,421,960,697,310 is 497763051840.
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.
684 x 421 x 960 x 697 x 310 = 59731566220800
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.
684 : 1, 2, 3, 4, 6, 9, 12, 18, 19, 36, 38, 57, 76, 114, 171, 228, 342, 684
421 : 1, 421
960 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 32, 40, 48, 60, 64, 80, 96, 120, 160, 192, 240, 320, 480, 960
697 : 1, 17, 41, 697
310 : 1, 2, 5, 10, 31, 62, 155, 310
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 684,421,960,697,310, is 1.
Now, the common factors can be found like this.
684:2x 2x 3x 3x 19
421:421
960:2x 2x 2x 2x 2x 2x 3x 5
697:17x 41
310:2x 5x 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 3x 5 = 120
Therefore, the value for common factors is 120.
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 = 59731566220800/(1x120)
LCM = 59731566220800/120
LCM = 497763051840
Thus, we can understand that the LCM of 684,421,960,697,310 is 497763051840.
