Find LCM of 777,840,889,248 with Prime Factorization
| 2 | 777, 840, 889, 248 |
| 2 | 777, 420, 889, 124 |
| 2 | 777, 210, 889, 62 |
| 3 | 777, 105, 889, 31 |
| 7 | 259, 35, 889, 31 |
| 37, 5, 127, 31 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 7 x 37 x 5 x 127 x 31 = 122361960
Therefore, the lowest common multiple of 777,840,889,248 is 122361960.
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.
777 x 840 x 889 x 248 = 143897664960
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.
777 : 1, 3, 7, 21, 37, 111, 259, 777
840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840
889 : 1, 7, 127, 889
248 : 1, 2, 4, 8, 31, 62, 124, 248
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 777,840,889,248, is 1.
Now, the common factors can be found like this.
777:3x 7x 37
840:2x 2x 2x 3x 5x 7
889:7x 127
248:2x 2x 2x 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 3x 7x 7 = 1176
Therefore, the value for common factors is 1176.
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 = 143897664960/(1x1176)
LCM = 143897664960/1176
LCM = 122361960
Thus, we can understand that the LCM of 777,840,889,248 is 122361960.
