GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(787, 372) = 292764
GCD(787, 372) = ( 787 x 372 ) / 292764
= 787 / 372
= 787
Step2:
LCM(1, 815) = 815
GCD(1, 815) = ( 1 x 815 ) / 815
= 1 / 815
= 1
Step3:
LCM(1, 380) = 380
GCD(1, 380) = ( 1 x 380 ) / 380
= 1 / 380
= 1
So, Greatest Common Divisor of 787, 372, 815, 380 is 1
