Find LCM of 609,702,840,168,355 with Prime Factorization
2 | 609, 702, 840, 168, 355 |
2 | 609, 351, 420, 84, 355 |
2 | 609, 351, 210, 42, 355 |
3 | 609, 351, 105, 21, 355 |
5 | 203, 117, 35, 7, 355 |
7 | 203, 117, 7, 7, 71 |
29, 117, 1, 1, 71 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 5 x 7 x 29 x 117 x 1 x 1 x 71 = 202358520
Therefore, the lowest common multiple of 609,702,840,168,355 is 202358520.
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.
609 x 702 x 840 x 168 x 355 = 21417625756800
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.
609 : 1, 3, 7, 21, 29, 87, 203, 609
702 : 1, 2, 3, 6, 9, 13, 18, 26, 27, 39, 54, 78, 117, 234, 351, 702
840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840
168 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 21, 24, 28, 42, 56, 84, 168
355 : 1, 5, 71, 355
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 609,702,840,168,355, is 1.
Now, the common factors can be found like this.
609:3x 7x 29
702:2x 3x 3x 3x 13
840:2x 2x 2x 3x 5x 7
168:2x 2x 2x 3x 7
355:5x 71
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 5x 7x 7 = 105840
Therefore, the value for common factors is 105840.
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 = 21417625756800/(1x105840)
LCM = 21417625756800/105840
LCM = 202358520
Thus, we can understand that the LCM of 609,702,840,168,355 is 202358520.
