Find LCM of 708,420,218,715,173 with Prime Factorization
| 2 | 708, 420, 218, 715, 173 |
| 2 | 354, 210, 109, 715, 173 |
| 3 | 177, 105, 109, 715, 173 |
| 5 | 59, 35, 109, 715, 173 |
| 59, 7, 109, 143, 173 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 59 x 7 x 109 x 143 x 173 = 66820533780
Therefore, the lowest common multiple of 708,420,218,715,173 is 66820533780.
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.
708 x 420 x 218 x 715 x 173 = 8018464053600
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.
708 : 1, 2, 3, 4, 6, 12, 59, 118, 177, 236, 354, 708
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
218 : 1, 2, 109, 218
715 : 1, 5, 11, 13, 55, 65, 143, 715
173 : 1, 173
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 708,420,218,715,173, is 1.
Now, the common factors can be found like this.
708:2x 2x 3x 59
420:2x 2x 3x 5x 7
218:2x 109
715:5x 11x 13
173:173
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 5 = 120
Therefore, the value for common factors is 120.
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 = 8018464053600/(1x120)
LCM = 8018464053600/120
LCM = 66820533780
Thus, we can understand that the LCM of 708,420,218,715,173 is 66820533780.
