Given numbers are 690, 691, 735
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(690, 691) = 476790
GCD(690, 691) = ( 690 x 691 ) / 476790
= 690 / 691
= 690
Step2:
LCM(1, 735) = 735
GCD(1, 735) = ( 1 x 735 ) / 735
= 1 / 735
= 1
So, Greatest Common Divisor of 690, 691, 735 is 1
