Given numbers are 425, 971, 457, 215
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(425, 971) = 412675
GCD(425, 971) = ( 425 x 971 ) / 412675
= 425 / 971
= 425
Step2:
LCM(1, 457) = 457
GCD(1, 457) = ( 1 x 457 ) / 457
= 1 / 457
= 1
Step3:
LCM(1, 215) = 215
GCD(1, 215) = ( 1 x 215 ) / 215
= 1 / 215
= 1
So, Greatest Common Divisor of 425, 971, 457, 215 is 1
