GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(171, 207) = 3933
GCD(171, 207) = ( 171 x 207 ) / 3933
= 171 / 207
= 171
Step2:
LCM(9, 987) = 2961
GCD(9, 987) = ( 9 x 987 ) / 2961
= 9 / 987
= 9
Step3:
LCM(3, 800) = 2400
GCD(3, 800) = ( 3 x 800 ) / 2400
= 3 / 800
= 3
So, Greatest Common Divisor of 171, 207, 987, 800 is 1
