Find LCM of 390,279,616,882,370 with Prime Factorization
| 2 | 390, 279, 616, 882, 370 |
| 3 | 195, 279, 308, 441, 185 |
| 3 | 65, 93, 308, 147, 185 |
| 5 | 65, 31, 308, 49, 185 |
| 7 | 13, 31, 308, 49, 37 |
| 13, 31, 44, 7, 37 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 5 x 7 x 13 x 31 x 44 x 7 x 37 = 2893330440
Therefore, the lowest common multiple of 390,279,616,882,370 is 2893330440.
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.
390 x 279 x 616 x 882 x 370 = 21873578126400
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.
390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390
279 : 1, 3, 9, 31, 93, 279
616 : 1, 2, 4, 7, 8, 11, 14, 22, 28, 44, 56, 77, 88, 154, 308, 616
882 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 42, 49, 63, 98, 126, 147, 294, 441, 882
370 : 1, 2, 5, 10, 37, 74, 185, 370
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 390,279,616,882,370, is 1.
Now, the common factors can be found like this.
390:2x 3x 5x 13
279:3x 3x 31
616:2x 2x 2x 7x 11
882:2x 3x 3x 7x 7
370:2x 5x 37
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 2x 3x 3x 3x 5x 7 = 7560
Therefore, the value for common factors is 7560.
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 = 21873578126400/(1x7560)
LCM = 21873578126400/7560
LCM = 2893330440
Thus, we can understand that the LCM of 390,279,616,882,370 is 2893330440.
