GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(639, 665) = 424935
GCD(639, 665) = ( 639 x 665 ) / 424935
= 639 / 665
= 639
Step2:
LCM(1, 260) = 260
GCD(1, 260) = ( 1 x 260 ) / 260
= 1 / 260
= 1
Step3:
LCM(1, 848) = 848
GCD(1, 848) = ( 1 x 848 ) / 848
= 1 / 848
= 1
So, Greatest Common Divisor of 639, 665, 260, 848 is 1
