GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(639, 286) = 182754
GCD(639, 286) = ( 639 x 286 ) / 182754
= 639 / 286
= 639
Step2:
LCM(1, 586) = 586
GCD(1, 586) = ( 1 x 586 ) / 586
= 1 / 586
= 1
Step3:
LCM(1, 263) = 263
GCD(1, 263) = ( 1 x 263 ) / 263
= 1 / 263
= 1
So, Greatest Common Divisor of 639, 286, 586, 263 is 1
