GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(690, 977) = 674130
GCD(690, 977) = ( 690 x 977 ) / 674130
= 690 / 977
= 690
Step2:
LCM(1, 732) = 732
GCD(1, 732) = ( 1 x 732 ) / 732
= 1 / 732
= 1
Step3:
LCM(1, 288) = 288
GCD(1, 288) = ( 1 x 288 ) / 288
= 1 / 288
= 1
So, Greatest Common Divisor of 690, 977, 732, 288 is 1
