The LCM of 756,363,209,770 is 8690220.
Find LCM of 756,363,209,770 with Prime Factorization
| 2 | 756, 363, 209, 770 |
| 3 | 378, 363, 209, 385 |
| 7 | 126, 121, 209, 385 |
| 11 | 18, 121, 209, 55 |
| 18, 11, 19, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 11 x 18 x 11 x 19 x 5 = 8690220
Therefore, the lowest common multiple of 756,363,209,770 is 8690220.
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.
756 x 363 x 209 x 770 = 44163698040
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.
756 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 27, 28, 36, 42, 54, 63, 84, 108, 126, 189, 252, 378, 756
363 : 1, 3, 11, 33, 121, 363
209 : 1, 11, 19, 209
770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 756,363,209,770, is 1.
Now, the common factors can be found like this.
756:2x 2x 3x 3x 3x 7
363:3x 11x 11
209:11x 19
770:2x 5x 7x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 7x 11x 11 = 5082
Therefore, the value for common factors is 5082.
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 = 44163698040/(1x5082)
LCM = 44163698040/5082
LCM = 8690220
Thus, we can understand that the LCM of 756,363,209,770 is 8690220.
