GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(215, 778) = 167270
GCD(215, 778) = ( 215 x 778 ) / 167270
= 215 / 778
= 215
Step2:
LCM(1, 209) = 209
GCD(1, 209) = ( 1 x 209 ) / 209
= 1 / 209
= 1
Step3:
LCM(1, 983) = 983
GCD(1, 983) = ( 1 x 983 ) / 983
= 1 / 983
= 1
So, Greatest Common Divisor of 215, 778, 209, 983 is 1
