GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(145, 980) = 28420
GCD(145, 980) = ( 145 x 980 ) / 28420
= 145 / 980
= 145
Step2:
LCM(5, 999) = 4995
GCD(5, 999) = ( 5 x 999 ) / 4995
= 5 / 999
= 5
Step3:
LCM(1, 764) = 764
GCD(1, 764) = ( 1 x 764 ) / 764
= 1 / 764
= 1
So, Greatest Common Divisor of 145, 980, 999, 764 is 1
