Find LCM of 736,972,645,126,942 with Prime Factorization
| 2 | 736, 972, 645, 126, 942 |
| 2 | 368, 486, 645, 63, 471 |
| 3 | 184, 243, 645, 63, 471 |
| 3 | 184, 81, 215, 21, 157 |
| 184, 27, 215, 7, 157 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 184 x 27 x 215 x 7 x 157 = 42259099680
Therefore, the lowest common multiple of 736,972,645,126,942 is 42259099680.
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.
736 x 972 x 645 x 126 x 942 = 54767793185280
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.
736 : 1, 2, 4, 8, 16, 23, 32, 46, 92, 184, 368, 736
972 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 81, 108, 162, 243, 324, 486, 972
645 : 1, 3, 5, 15, 43, 129, 215, 645
126 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 42, 63, 126
942 : 1, 2, 3, 6, 157, 314, 471, 942
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 736,972,645,126,942, is 1.
Now, the common factors can be found like this.
736:2x 2x 2x 2x 2x 23
972:2x 2x 3x 3x 3x 3x 3
645:3x 5x 43
126:2x 3x 3x 7
942:2x 3x 157
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 3x 3x 3 = 1296
Therefore, the value for common factors is 1296.
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 = 54767793185280/(1x1296)
LCM = 54767793185280/1296
LCM = 42259099680
Thus, we can understand that the LCM of 736,972,645,126,942 is 42259099680.
