The LCM of 620,775,832,744 is 1934400.
Find LCM of 620,775,832,744 with Prime Factorization
| 2 | 620, 775, 832, 744 |
| 2 | 310, 775, 416, 372 |
| 2 | 155, 775, 208, 186 |
| 5 | 155, 775, 104, 93 |
| 31 | 31, 155, 104, 93 |
| 1, 5, 104, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 5 x 31 x 1 x 5 x 104 x 3 = 1934400
Therefore, the lowest common multiple of 620,775,832,744 is 1934400.
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.
620 x 775 x 832 x 744 = 297433344000
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.
620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620
775 : 1, 5, 25, 31, 155, 775
832 : 1, 2, 4, 8, 13, 16, 26, 32, 52, 64, 104, 208, 416, 832
744 : 1, 2, 3, 4, 6, 8, 12, 24, 31, 62, 93, 124, 186, 248, 372, 744
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 620,775,832,744, is 1.
Now, the common factors can be found like this.
620:2x 2x 5x 31
775:5x 5x 31
832:2x 2x 2x 2x 2x 2x 13
744:2x 2x 2x 3x 31
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 2x 2x 5x 31x 31 = 153760
Therefore, the value for common factors is 153760.
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 = 297433344000/(1x153760)
LCM = 297433344000/153760
LCM = 1934400
Thus, we can understand that the LCM of 620,775,832,744 is 1934400.
