Given numbers are 281, 715, 392, 191
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(281, 715) = 200915
GCD(281, 715) = ( 281 x 715 ) / 200915
= 281 / 715
= 281
Step2:
LCM(1, 392) = 392
GCD(1, 392) = ( 1 x 392 ) / 392
= 1 / 392
= 1
Step3:
LCM(1, 191) = 191
GCD(1, 191) = ( 1 x 191 ) / 191
= 1 / 191
= 1
So, Greatest Common Divisor of 281, 715, 392, 191 is 1
