Given numbers are 262, 309, 840, 203
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(262, 309) = 80958
GCD(262, 309) = ( 262 x 309 ) / 80958
= 262 / 309
= 262
Step2:
LCM(1, 840) = 840
GCD(1, 840) = ( 1 x 840 ) / 840
= 1 / 840
= 1
Step3:
LCM(1, 203) = 203
GCD(1, 203) = ( 1 x 203 ) / 203
= 1 / 203
= 1
So, Greatest Common Divisor of 262, 309, 840, 203 is 1
