Given numbers are 102, 190, 69, 990
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(102, 190) = 9690
GCD(102, 190) = ( 102 x 190 ) / 9690
= 102 / 190
= 102
Step2:
LCM(2, 69) = 138
GCD(2, 69) = ( 2 x 69 ) / 138
= 2 / 69
= 2
Step3:
LCM(1, 990) = 990
GCD(1, 990) = ( 1 x 990 ) / 990
= 1 / 990
= 1
So, Greatest Common Divisor of 102, 190, 69, 990 is 1
