Given numbers are 201, 121, 646, 801
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(201, 121) = 24321
GCD(201, 121) = ( 201 x 121 ) / 24321
= 201 / 121
= 201
Step2:
LCM(1, 646) = 646
GCD(1, 646) = ( 1 x 646 ) / 646
= 1 / 646
= 1
Step3:
LCM(1, 801) = 801
GCD(1, 801) = ( 1 x 801 ) / 801
= 1 / 801
= 1
So, Greatest Common Divisor of 201, 121, 646, 801 is 1
