Given numbers are 987, 891, 354, 610
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(987, 891) = 293139
GCD(987, 891) = ( 987 x 891 ) / 293139
= 987 / 891
= 987
Step2:
LCM(3, 354) = 354
GCD(3, 354) = ( 3 x 354 ) / 354
= 3 / 354
= 3
Step3:
LCM(3, 610) = 1830
GCD(3, 610) = ( 3 x 610 ) / 1830
= 3 / 610
= 3
So, Greatest Common Divisor of 987, 891, 354, 610 is 1
