Given numbers are 815, 980, 770, 993
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(815, 980) = 159740
GCD(815, 980) = ( 815 x 980 ) / 159740
= 815 / 980
= 815
Step2:
LCM(5, 770) = 770
GCD(5, 770) = ( 5 x 770 ) / 770
= 5 / 770
= 5
Step3:
LCM(5, 993) = 4965
GCD(5, 993) = ( 5 x 993 ) / 4965
= 5 / 993
= 5
So, Greatest Common Divisor of 815, 980, 770, 993 is 1
