Given numbers are 891, 690, 102, 528
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(891, 690) = 204930
GCD(891, 690) = ( 891 x 690 ) / 204930
= 891 / 690
= 891
Step2:
LCM(3, 102) = 102
GCD(3, 102) = ( 3 x 102 ) / 102
= 3 / 102
= 3
Step3:
LCM(3, 528) = 528
GCD(3, 528) = ( 3 x 528 ) / 528
= 3 / 528
= 3
So, Greatest Common Divisor of 891, 690, 102, 528 is 3
