The LCM of 745,616,254,385 is 58282840.
Find LCM of 745,616,254,385 with Prime Factorization
| 2 | 745, 616, 254, 385 |
| 5 | 745, 308, 127, 385 |
| 7 | 149, 308, 127, 77 |
| 11 | 149, 44, 127, 11 |
| 149, 4, 127, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 7 x 11 x 149 x 4 x 127 x 1 = 58282840
Therefore, the lowest common multiple of 745,616,254,385 is 58282840.
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.
745 x 616 x 254 x 385 = 44877786800
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.
745 : 1, 5, 149, 745
616 : 1, 2, 4, 7, 8, 11, 14, 22, 28, 44, 56, 77, 88, 154, 308, 616
254 : 1, 2, 127, 254
385 : 1, 5, 7, 11, 35, 55, 77, 385
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 745,616,254,385, is 1.
Now, the common factors can be found like this.
745:5x 149
616:2x 2x 2x 7x 11
254:2x 127
385:5x 7x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 7x 11 = 770
Therefore, the value for common factors is 770.
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 = 44877786800/(1x770)
LCM = 44877786800/770
LCM = 58282840
Thus, we can understand that the LCM of 745,616,254,385 is 58282840.
