The LCM of 847,240,791,224 is 45941280.
Find LCM of 847,240,791,224 with Prime Factorization
| 2 | 847, 240, 791, 224 |
| 2 | 847, 120, 791, 112 |
| 2 | 847, 60, 791, 56 |
| 2 | 847, 30, 791, 28 |
| 7 | 847, 15, 791, 14 |
| 121, 15, 113, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 7 x 121 x 15 x 113 x 2 = 45941280
Therefore, the lowest common multiple of 847,240,791,224 is 45941280.
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.
847 x 240 x 791 x 224 = 36017963520
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.
847 : 1, 7, 11, 77, 121, 847
240 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 40, 48, 60, 80, 120, 240
791 : 1, 7, 113, 791
224 : 1, 2, 4, 7, 8, 14, 16, 28, 32, 56, 112, 224
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 847,240,791,224, is 1.
Now, the common factors can be found like this.
847:7x 11x 11
240:2x 2x 2x 2x 3x 5
791:7x 113
224:2x 2x 2x 2x 2x 7
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 7x 7 = 784
Therefore, the value for common factors is 784.
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 = 36017963520/(1x784)
LCM = 36017963520/784
LCM = 45941280
Thus, we can understand that the LCM of 847,240,791,224 is 45941280.
