Given numbers are 630, 809, 285, 187
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(630, 809) = 509670
GCD(630, 809) = ( 630 x 809 ) / 509670
= 630 / 809
= 630
Step2:
LCM(1, 285) = 285
GCD(1, 285) = ( 1 x 285 ) / 285
= 1 / 285
= 1
Step3:
LCM(1, 187) = 187
GCD(1, 187) = ( 1 x 187 ) / 187
= 1 / 187
= 1
So, Greatest Common Divisor of 630, 809, 285, 187 is 1
