Find LCM of 789,708,140,714,730 with Prime Factorization
2 | 789, 708, 140, 714, 730 |
2 | 789, 354, 70, 357, 365 |
3 | 789, 177, 35, 357, 365 |
5 | 263, 59, 35, 119, 365 |
7 | 263, 59, 7, 119, 73 |
263, 59, 1, 17, 73 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 7 x 263 x 59 x 1 x 17 x 73 = 8087770740
Therefore, the lowest common multiple of 789,708,140,714,730 is 8087770740.
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.
789 x 708 x 140 x 714 x 730 = 40762364529600
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.
789 : 1, 3, 263, 789
708 : 1, 2, 3, 4, 6, 12, 59, 118, 177, 236, 354, 708
140 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 70, 140
714 : 1, 2, 3, 6, 7, 14, 17, 21, 34, 42, 51, 102, 119, 238, 357, 714
730 : 1, 2, 5, 10, 73, 146, 365, 730
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 789,708,140,714,730, is 1.
Now, the common factors can be found like this.
789:3x 263
708:2x 2x 3x 59
140:2x 2x 5x 7
714:2x 3x 7x 17
730:2x 5x 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 2x 3x 3x 5x 7 = 5040
Therefore, the value for common factors is 5040.
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 = 40762364529600/(1x5040)
LCM = 40762364529600/5040
LCM = 8087770740
Thus, we can understand that the LCM of 789,708,140,714,730 is 8087770740.
