Find LCM of 853,774,473,645,657 with Prime Factorization
| 3 | 853, 774, 473, 645, 657 |
| 3 | 853, 258, 473, 215, 219 |
| 43 | 853, 86, 473, 215, 73 |
| 853, 2, 11, 5, 73 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 43 x 853 x 2 x 11 x 5 x 73 = 2650791330
Therefore, the lowest common multiple of 853,774,473,645,657 is 2650791330.
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.
853 x 774 x 473 x 645 x 657 = 132335455567590
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.
853 : 1, 853
774 : 1, 2, 3, 6, 9, 18, 43, 86, 129, 258, 387, 774
473 : 1, 11, 43, 473
645 : 1, 3, 5, 15, 43, 129, 215, 645
657 : 1, 3, 9, 73, 219, 657
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 853,774,473,645,657, is 1.
Now, the common factors can be found like this.
853:853
774:2x 3x 3x 43
473:11x 43
645:3x 5x 43
657:3x 3x 73
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 3x 43x 43 = 49923
Therefore, the value for common factors is 49923.
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 = 132335455567590/(1x49923)
LCM = 132335455567590/49923
LCM = 2650791330
Thus, we can understand that the LCM of 853,774,473,645,657 is 2650791330.
