Find LCM of 972,492,221,427,812 with Prime Factorization
| 2 | 972, 492, 221, 427, 812 |
| 2 | 486, 246, 221, 427, 406 |
| 3 | 243, 123, 221, 427, 203 |
| 7 | 81, 41, 221, 427, 203 |
| 81, 41, 221, 61, 29 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 7 x 81 x 41 x 221 x 61 x 29 = 109060696836
Therefore, the lowest common multiple of 972,492,221,427,812 is 109060696836.
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.
972 x 492 x 221 x 427 x 812 = 36644394136896
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.
972 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 81, 108, 162, 243, 324, 486, 972
492 : 1, 2, 3, 4, 6, 12, 41, 82, 123, 164, 246, 492
221 : 1, 13, 17, 221
427 : 1, 7, 61, 427
812 : 1, 2, 4, 7, 14, 28, 29, 58, 116, 203, 406, 812
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 972,492,221,427,812, is 1.
Now, the common factors can be found like this.
972:2x 2x 3x 3x 3x 3x 3
492:2x 2x 3x 41
221:13x 17
427:7x 61
812:2x 2x 7x 29
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 7 = 336
Therefore, the value for common factors is 336.
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 = 36644394136896/(1x336)
LCM = 36644394136896/336
LCM = 109060696836
Thus, we can understand that the LCM of 972,492,221,427,812 is 109060696836.
