Find LCM of 742,774,420,185,819 with Prime Factorization
| 2 | 742, 774, 420, 185, 819 |
| 3 | 371, 387, 210, 185, 819 |
| 3 | 371, 129, 70, 185, 273 |
| 5 | 371, 43, 70, 185, 91 |
| 7 | 371, 43, 14, 37, 91 |
| 53, 43, 2, 37, 13 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 5 x 7 x 53 x 43 x 2 x 37 x 13 = 1381210740
Therefore, the lowest common multiple of 742,774,420,185,819 is 1381210740.
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.
742 x 774 x 420 x 185 x 819 = 36546836180400
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.
742 : 1, 2, 7, 14, 53, 106, 371, 742
774 : 1, 2, 3, 6, 9, 18, 43, 86, 129, 258, 387, 774
420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420
185 : 1, 5, 37, 185
819 : 1, 3, 7, 9, 13, 21, 39, 63, 91, 117, 273, 819
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 742,774,420,185,819, is 1.
Now, the common factors can be found like this.
742:2x 7x 53
774:2x 3x 3x 43
420:2x 2x 3x 5x 7
185:5x 37
819:3x 3x 7x 13
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 3x 5x 7x 7 = 26460
Therefore, the value for common factors is 26460.
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 = 36546836180400/(1x26460)
LCM = 36546836180400/26460
LCM = 1381210740
Thus, we can understand that the LCM of 742,774,420,185,819 is 1381210740.
