Find LCM of 729,708,180,698,392 with Prime Factorization
2 | 729, 708, 180, 698, 392 |
2 | 729, 354, 90, 349, 196 |
3 | 729, 177, 45, 349, 98 |
3 | 243, 59, 15, 349, 98 |
81, 59, 5, 349, 98 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 81 x 59 x 5 x 349 x 98 = 29421244440
Therefore, the lowest common multiple of 729,708,180,698,392 is 29421244440.
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.
729 x 708 x 180 x 698 x 392 = 25419955196160
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.
729 : 1, 3, 9, 27, 81, 243, 729
708 : 1, 2, 3, 4, 6, 12, 59, 118, 177, 236, 354, 708
180 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 30, 36, 45, 60, 90, 180
698 : 1, 2, 349, 698
392 : 1, 2, 4, 7, 8, 14, 28, 49, 56, 98, 196, 392
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 729,708,180,698,392, is 1.
Now, the common factors can be found like this.
729:3x 3x 3x 3x 3x 3
708:2x 2x 3x 59
180:2x 2x 3x 3x 5
698:2x 349
392:2x 2x 2x 7x 7
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 2x 3x 3x 3 = 864
Therefore, the value for common factors is 864.
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 = 25419955196160/(1x864)
LCM = 25419955196160/864
LCM = 29421244440
Thus, we can understand that the LCM of 729,708,180,698,392 is 29421244440.
