Find LCM of 620,310,297,943,666 with Prime Factorization
| 2 | 620, 310, 297, 943, 666 |
| 3 | 310, 155, 297, 943, 333 |
| 3 | 310, 155, 99, 943, 111 |
| 5 | 310, 155, 33, 943, 37 |
| 31 | 62, 31, 33, 943, 37 |
| 2, 1, 33, 943, 37 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 5 x 31 x 2 x 1 x 33 x 943 x 37 = 6424828740
Therefore, the lowest common multiple of 620,310,297,943,666 is 6424828740.
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.
620 x 310 x 297 x 943 x 666 = 35850544369200
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.
620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620
310 : 1, 2, 5, 10, 31, 62, 155, 310
297 : 1, 3, 9, 11, 27, 33, 99, 297
943 : 1, 23, 41, 943
666 : 1, 2, 3, 6, 9, 18, 37, 74, 111, 222, 333, 666
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 620,310,297,943,666, is 1.
Now, the common factors can be found like this.
620:2x 2x 5x 31
310:2x 5x 31
297:3x 3x 3x 11
943:23x 41
666:2x 3x 3x 37
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 3x 3x 5x 31 = 5580
Therefore, the value for common factors is 5580.
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 = 35850544369200/(1x5580)
LCM = 35850544369200/5580
LCM = 6424828740
Thus, we can understand that the LCM of 620,310,297,943,666 is 6424828740.
