Given numbers are 361, 621, 191, 755
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(361, 621) = 224181
GCD(361, 621) = ( 361 x 621 ) / 224181
= 361 / 621
= 361
Step2:
LCM(1, 191) = 191
GCD(1, 191) = ( 1 x 191 ) / 191
= 1 / 191
= 1
Step3:
LCM(1, 755) = 755
GCD(1, 755) = ( 1 x 755 ) / 755
= 1 / 755
= 1
So, Greatest Common Divisor of 361, 621, 191, 755 is 1
