The answer is 42.
But more important is how to get this answer. First write out the prime factors of each number.
3: 3
6: 2, 3
7: 7
To get the LCM, each factor needs to be included so here it's 2x3x7=42
The LCM of 7, 6, 12, and 3 is 84.
The LCM is: 84
Thirty-five is the LCM of 3/5 + 6/7.
lcm(6, 7, 45) = 630. 6 = 2 x 3 7 = 7 45 = 3^2 x 5 lcm = 2 x 3^2 x 5 x 7 = 630
The LCM is: 126
The Least Common Multiple (LCM) of 7, 3, and 6 is 42.
The LCM of 7, 6, 12, and 3 is 84.
The LCM is 42.
The LCM is: 84
Thirty-five is the LCM of 3/5 + 6/7.
lcm(6, 7, 45) = 630. 6 = 2 x 3 7 = 7 45 = 3^2 x 5 lcm = 2 x 3^2 x 5 x 7 = 630
The LCM is: 126
The LCM is: 84

42
the lcm of 1 2 3 4 5 6 7 is 420
lcm(2, 3, 4, 5, 6, 7, 8) = 840
