Given numbers are 971, 257, 514, 420
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(971, 257) = 249547
GCD(971, 257) = ( 971 x 257 ) / 249547
= 971 / 257
= 971
Step2:
LCM(1, 514) = 514
GCD(1, 514) = ( 1 x 514 ) / 514
= 1 / 514
= 1
Step3:
LCM(1, 420) = 420
GCD(1, 420) = ( 1 x 420 ) / 420
= 1 / 420
= 1
So, Greatest Common Divisor of 971, 257, 514, 420 is 1
