Given numbers are 981, 405, 135, 163
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(981, 405) = 44145
GCD(981, 405) = ( 981 x 405 ) / 44145
= 981 / 405
= 981
Step2:
LCM(9, 135) = 135
GCD(9, 135) = ( 9 x 135 ) / 135
= 9 / 135
= 9
Step3:
LCM(9, 163) = 1467
GCD(9, 163) = ( 9 x 163 ) / 1467
= 9 / 163
= 9
So, Greatest Common Divisor of 981, 405, 135, 163 is 1
