GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(186, 225) = 13950
GCD(186, 225) = ( 186 x 225 ) / 13950
= 186 / 225
= 186
Step2:
LCM(3, 938) = 2814
GCD(3, 938) = ( 3 x 938 ) / 2814
= 3 / 938
= 3
Step3:
LCM(1, 645) = 645
GCD(1, 645) = ( 1 x 645 ) / 645
= 1 / 645
= 1
So, Greatest Common Divisor of 186, 225, 938, 645 is 1
