Find LCM of 987,163,836,893,140 with Prime Factorization
2 | 987, 163, 836, 893, 140 |
2 | 987, 163, 418, 893, 70 |
7 | 987, 163, 209, 893, 35 |
19 | 141, 163, 209, 893, 5 |
47 | 141, 163, 11, 47, 5 |
3, 163, 11, 1, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 19 x 47 x 3 x 163 x 11 x 1 x 5 = 672482580
Therefore, the lowest common multiple of 987,163,836,893,140 is 672482580.
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.
987 x 163 x 836 x 893 x 140 = 16814754430320
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.
987 : 1, 3, 7, 21, 47, 141, 329, 987
163 : 1, 163
836 : 1, 2, 4, 11, 19, 22, 38, 44, 76, 209, 418, 836
893 : 1, 19, 47, 893
140 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 70, 140
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 987,163,836,893,140, is 1.
Now, the common factors can be found like this.
987:3x 7x 47
163:163
836:2x 2x 11x 19
893:19x 47
140:2x 2x 5x 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 7x 19x 47 = 25004
Therefore, the value for common factors is 25004.
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 = 16814754430320/(1x25004)
LCM = 16814754430320/25004
LCM = 672482580
Thus, we can understand that the LCM of 987,163,836,893,140 is 672482580.
