Find LCM of 740,646,222,779,115 with Prime Factorization
| 2 | 740, 646, 222, 779, 115 |
| 5 | 370, 323, 111, 779, 115 |
| 19 | 74, 323, 111, 779, 23 |
| 37 | 74, 17, 111, 41, 23 |
| 2, 17, 3, 41, 23 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 19 x 37 x 2 x 17 x 3 x 41 x 23 = 676187580
Therefore, the lowest common multiple of 740,646,222,779,115 is 676187580.
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.
740 x 646 x 222 x 779 x 115 = 9507197374800
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.
740 : 1, 2, 4, 5, 10, 20, 37, 74, 148, 185, 370, 740
646 : 1, 2, 17, 19, 34, 38, 323, 646
222 : 1, 2, 3, 6, 37, 74, 111, 222
779 : 1, 19, 41, 779
115 : 1, 5, 23, 115
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 740,646,222,779,115, is 1.
Now, the common factors can be found like this.
740:2x 2x 5x 37
646:2x 17x 19
222:2x 3x 37
779:19x 41
115:5x 23
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 5x 19x 37 = 14060
Therefore, the value for common factors is 14060.
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 = 9507197374800/(1x14060)
LCM = 9507197374800/14060
LCM = 676187580
Thus, we can understand that the LCM of 740,646,222,779,115 is 676187580.
