Given numbers are 997, 639, 360, 860
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(997, 639) = 637083
GCD(997, 639) = ( 997 x 639 ) / 637083
= 997 / 639
= 997
Step2:
LCM(1, 360) = 360
GCD(1, 360) = ( 1 x 360 ) / 360
= 1 / 360
= 1
Step3:
LCM(1, 860) = 860
GCD(1, 860) = ( 1 x 860 ) / 860
= 1 / 860
= 1
So, Greatest Common Divisor of 997, 639, 360, 860 is 1
