Given numbers are 221, 765, 426, 188
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(221, 765) = 9945
GCD(221, 765) = ( 221 x 765 ) / 9945
= 221 / 765
= 221
Step2:
LCM(17, 426) = 7242
GCD(17, 426) = ( 17 x 426 ) / 7242
= 17 / 426
= 17
Step3:
LCM(1, 188) = 188
GCD(1, 188) = ( 1 x 188 ) / 188
= 1 / 188
= 1
So, Greatest Common Divisor of 221, 765, 426, 188 is 1
