The LCM of 708,777,771,252 is 141379812.
Find LCM of 708,777,771,252 with Prime Factorization
| 2 | 708, 777, 771, 252 |
| 2 | 354, 777, 771, 126 |
| 3 | 177, 777, 771, 63 |
| 7 | 59, 259, 257, 21 |
| 59, 37, 257, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 7 x 59 x 37 x 257 x 3 = 141379812
Therefore, the lowest common multiple of 708,777,771,252 is 141379812.
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.
708 x 777 x 771 x 252 = 106883137872
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.
708 : 1, 2, 3, 4, 6, 12, 59, 118, 177, 236, 354, 708
777 : 1, 3, 7, 21, 37, 111, 259, 777
771 : 1, 3, 257, 771
252 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 28, 36, 42, 63, 84, 126, 252
3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 708,777,771,252, is 3.
Now, the common factors can be found like this.
708:2x 2x 3x 59
777:3x 7x 37
771:3x 257
252:2x 2x 3x 3x 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 3x 3x 7 = 252
Therefore, the value for common factors is 252.
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 = 106883137872/(3x252)
LCM = 106883137872/756
LCM = 141379812
Thus, we can understand that the LCM of 708,777,771,252 is 141379812.
