Find LCM of 987,446,681,966,322 with Prime Factorization
| 2 | 987, 446, 681, 966, 322 |
| 3 | 987, 223, 681, 483, 161 |
| 7 | 329, 223, 227, 161, 161 |
| 23 | 47, 223, 227, 23, 23 |
| 47, 223, 227, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 23 x 47 x 223 x 227 x 1 x 1 = 2298294642
Therefore, the lowest common multiple of 987,446,681,966,322 is 2298294642.
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 446 x 681 x 966 x 322 = 93246410215224
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
446 : 1, 2, 223, 446
681 : 1, 3, 227, 681
966 : 1, 2, 3, 6, 7, 14, 21, 23, 42, 46, 69, 138, 161, 322, 483, 966
322 : 1, 2, 7, 14, 23, 46, 161, 322
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 987,446,681,966,322, is 1.
Now, the common factors can be found like this.
987:3x 7x 47
446:2x 223
681:3x 227
966:2x 3x 7x 23
322:2x 7x 23
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 7x 7x 23 = 40572
Therefore, the value for common factors is 40572.
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 = 93246410215224/(1x40572)
LCM = 93246410215224/40572
LCM = 2298294642
Thus, we can understand that the LCM of 987,446,681,966,322 is 2298294642.
