Given numbers are 172, 694, 203, 641
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(172, 694) = 59684
GCD(172, 694) = ( 172 x 694 ) / 59684
= 172 / 694
= 172
Step2:
LCM(2, 203) = 406
GCD(2, 203) = ( 2 x 203 ) / 406
= 2 / 203
= 2
Step3:
LCM(1, 641) = 641
GCD(1, 641) = ( 1 x 641 ) / 641
= 1 / 641
= 1
So, Greatest Common Divisor of 172, 694, 203, 641 is 1
