Given numbers are 285, 221, 374, 109
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(285, 221) = 62985
GCD(285, 221) = ( 285 x 221 ) / 62985
= 285 / 221
= 285
Step2:
LCM(1, 374) = 374
GCD(1, 374) = ( 1 x 374 ) / 374
= 1 / 374
= 1
Step3:
LCM(1, 109) = 109
GCD(1, 109) = ( 1 x 109 ) / 109
= 1 / 109
= 1
So, Greatest Common Divisor of 285, 221, 374, 109 is 1
