Given numbers are 812,756,853,136,743
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 812,756,853,136,743 is 472429007064.
Find LCM of 812,756,853,136,743 with Prime Factorization
| 2 | 812, 756, 853, 136, 743 |
| 2 | 406, 378, 853, 68, 743 |
| 7 | 203, 189, 853, 34, 743 |
| 29, 27, 853, 34, 743 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 29 x 27 x 853 x 34 x 743 = 472429007064
Therefore, the lowest common multiple of 812,756,853,136,743 is 472429007064.
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.
812 x 756 x 853 x 136 x 743 = 52912048791168
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.
812 : 1, 2, 4, 7, 14, 28, 29, 58, 116, 203, 406, 812
756 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 27, 28, 36, 42, 54, 63, 84, 108, 126, 189, 252, 378, 756
853 : 1, 853
136 : 1, 2, 4, 8, 17, 34, 68, 136
743 : 1, 743
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 812,756,853,136,743, is 1.
Now, the common factors can be found like this.
812:2x 2x 7x 29
756:2x 2x 3x 3x 3x 7
853:853
136:2x 2x 2x 17
743:743
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 7 = 112
Therefore, the value for common factors is 112.
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 = 52912048791168/(1x112)
LCM = 52912048791168/112
LCM = 472429007064
Thus, we can understand that the LCM of 812,756,853,136,743 is 472429007064.
