Given numbers are 987, 155, 683, 551
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(987, 155) = 152985
GCD(987, 155) = ( 987 x 155 ) / 152985
= 987 / 155
= 987
Step2:
LCM(1, 683) = 683
GCD(1, 683) = ( 1 x 683 ) / 683
= 1 / 683
= 1
Step3:
LCM(1, 551) = 551
GCD(1, 551) = ( 1 x 551 ) / 551
= 1 / 551
= 1
So, Greatest Common Divisor of 987, 155, 683, 551 is 1
