GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(989, 202) = 199778
GCD(989, 202) = ( 989 x 202 ) / 199778
= 989 / 202
= 989
Step2:
LCM(1, 190) = 190
GCD(1, 190) = ( 1 x 190 ) / 190
= 1 / 190
= 1
Step3:
LCM(1, 770) = 770
GCD(1, 770) = ( 1 x 770 ) / 770
= 1 / 770
= 1
So, Greatest Common Divisor of 989, 202, 190, 770 is 1
