Find LCM of 861,748,492,232,743 with Prime Factorization
2 | 861, 748, 492, 232, 743 |
2 | 861, 374, 246, 116, 743 |
3 | 861, 187, 123, 58, 743 |
41 | 287, 187, 41, 58, 743 |
7, 187, 1, 58, 743 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 41 x 7 x 187 x 1 x 58 x 743 = 27753742632
Therefore, the lowest common multiple of 861,748,492,232,743 is 27753742632.
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.
861 x 748 x 492 x 232 x 743 = 54619365499776
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.
861 : 1, 3, 7, 21, 41, 123, 287, 861
748 : 1, 2, 4, 11, 17, 22, 34, 44, 68, 187, 374, 748
492 : 1, 2, 3, 4, 6, 12, 41, 82, 123, 164, 246, 492
232 : 1, 2, 4, 8, 29, 58, 116, 232
743 : 1, 743
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 861,748,492,232,743, is 1.
Now, the common factors can be found like this.
861:3x 7x 41
748:2x 2x 11x 17
492:2x 2x 3x 41
232:2x 2x 2x 29
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 3x 41 = 1968
Therefore, the value for common factors is 1968.
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 = 54619365499776/(1x1968)
LCM = 54619365499776/1968
LCM = 27753742632
Thus, we can understand that the LCM of 861,748,492,232,743 is 27753742632.
