Find LCM of 770,495,946,245 with Prime Factorization
| 2 | 770, 495, 946, 245 |
| 5 | 385, 495, 473, 245 |
| 7 | 77, 99, 473, 49 |
| 11 | 11, 99, 473, 7 |
| 1, 9, 43, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 7 x 11 x 1 x 9 x 43 x 7 = 2085930
Therefore, the lowest common multiple of 770,495,946,245 is 2085930.
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.
770 x 495 x 946 x 245 = 88339135500
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.
770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770
495 : 1, 3, 5, 9, 11, 15, 33, 45, 55, 99, 165, 495
946 : 1, 2, 11, 22, 43, 86, 473, 946
245 : 1, 5, 7, 35, 49, 245
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 770,495,946,245, is 1.
Now, the common factors can be found like this.
770:2x 5x 7x 11
495:3x 3x 5x 11
946:2x 11x 43
245:5x 7x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 5x 7x 11x 11 = 42350
Therefore, the value for common factors is 42350.
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 = 88339135500/(1x42350)
LCM = 88339135500/42350
LCM = 2085930
Thus, we can understand that the LCM of 770,495,946,245 is 2085930.
