GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(780, 989) = 771420
GCD(780, 989) = ( 780 x 989 ) / 771420
= 780 / 989
= 780
Step2:
LCM(1, 903) = 903
GCD(1, 903) = ( 1 x 903 ) / 903
= 1 / 903
= 1
Step3:
LCM(1, 435) = 435
GCD(1, 435) = ( 1 x 435 ) / 435
= 1 / 435
= 1
So, Greatest Common Divisor of 780, 989, 903, 435 is 1
