Find LCM of 373,738,780,169,644 with Prime Factorization
| 2 | 373, 738, 780, 169, 644 |
| 2 | 373, 369, 390, 169, 322 |
| 3 | 373, 369, 195, 169, 161 |
| 13 | 373, 123, 65, 169, 161 |
| 373, 123, 5, 13, 161 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 13 x 373 x 123 x 5 x 13 x 161 = 74899302660
Therefore, the lowest common multiple of 373,738,780,169,644 is 74899302660.
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.
373 x 738 x 780 x 169 x 644 = 23368582429920
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.
373 : 1, 373
738 : 1, 2, 3, 6, 9, 18, 41, 82, 123, 246, 369, 738
780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780
169 : 1, 13, 169
644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 373,738,780,169,644, is 1.
Now, the common factors can be found like this.
373:373
738:2x 3x 3x 41
780:2x 2x 3x 5x 13
169:13x 13
644:2x 2x 7x 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 2x 3x 13 = 312
Therefore, the value for common factors is 312.
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 = 23368582429920/(1x312)
LCM = 23368582429920/312
LCM = 74899302660
Thus, we can understand that the LCM of 373,738,780,169,644 is 74899302660.
