Find LCM of 737,668,917,420,438 with Prime Factorization
| 2 | 737, 668, 917, 420, 438 |
| 2 | 737, 334, 917, 210, 219 |
| 3 | 737, 167, 917, 105, 219 |
| 7 | 737, 167, 917, 35, 73 |
| 737, 167, 131, 5, 73 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 7 x 737 x 167 x 131 x 5 x 73 = 494341880340
Therefore, the lowest common multiple of 737,668,917,420,438 is 494341880340.
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.
737 x 668 x 917 x 420 x 438 = 83049435897120
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.
737 : 1, 11, 67, 737
668 : 1, 2, 4, 167, 334, 668
917 : 1, 7, 131, 917
420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420
438 : 1, 2, 3, 6, 73, 146, 219, 438
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 737,668,917,420,438, is 1.
Now, the common factors can be found like this.
737:11x 67
668:2x 2x 167
917:7x 131
420:2x 2x 3x 5x 7
438:2x 3x 73
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 3x 7 = 168
Therefore, the value for common factors is 168.
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 = 83049435897120/(1x168)
LCM = 83049435897120/168
LCM = 494341880340
Thus, we can understand that the LCM of 737,668,917,420,438 is 494341880340.
