Given numbers are 646, 902, 174, 161
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(646, 902) = 291346
GCD(646, 902) = ( 646 x 902 ) / 291346
= 646 / 902
= 646
Step2:
LCM(2, 174) = 174
GCD(2, 174) = ( 2 x 174 ) / 174
= 2 / 174
= 2
Step3:
LCM(2, 161) = 322
GCD(2, 161) = ( 2 x 161 ) / 322
= 2 / 161
= 2
So, Greatest Common Divisor of 646, 902, 174, 161 is 1
