Find LCM of 845,242,672,988,746 with Prime Factorization
2 | 845, 242, 672, 988, 746 |
2 | 845, 121, 336, 494, 373 |
13 | 845, 121, 168, 247, 373 |
65, 121, 168, 19, 373 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 13 x 65 x 121 x 168 x 19 x 373 = 486938131680
Therefore, the lowest common multiple of 845,242,672,988,746 is 486938131680.
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.
845 x 242 x 672 x 988 x 746 = 101283131389440
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.
845 : 1, 5, 13, 65, 169, 845
242 : 1, 2, 11, 22, 121, 242
672 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 16, 21, 24, 28, 32, 42, 48, 56, 84, 96, 112, 168, 224, 336, 672
988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988
746 : 1, 2, 373, 746
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 845,242,672,988,746, is 1.
Now, the common factors can be found like this.
845:5x 13x 13
242:2x 11x 11
672:2x 2x 2x 2x 2x 3x 7
988:2x 2x 13x 19
746:2x 373
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 13 = 208
Therefore, the value for common factors is 208.
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 = 101283131389440/(1x208)
LCM = 101283131389440/208
LCM = 486938131680
Thus, we can understand that the LCM of 845,242,672,988,746 is 486938131680.
