They're all prime numbers, therefore it's one.
1, but if you meant lowest common multiple, then 35
The lowest common denominator of 5/42 and 7/30 is 210.
prime factorizations: 2 = 1 x 2 5 = 1 x 5 7 = 1 x 7 so lowest common factor is 1.
The LCM of 5, 6, and 7 is 210.
5 and 7 are both prime numbers, so the least common multiple is 5*7=35
The LCM is: 35
It is 70
1 2/5
The least common multiple of 2 , 3 , 5 , 7 = 210
The Least Common Multiple (LCM) for 7 11 5 is 385
The lowest common denominator of any set of whole numbers is 1
