Given numbers are 154, 787, 809, 426
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(154, 787) = 121198
GCD(154, 787) = ( 154 x 787 ) / 121198
= 154 / 787
= 154
Step2:
LCM(1, 809) = 809
GCD(1, 809) = ( 1 x 809 ) / 809
= 1 / 809
= 1
Step3:
LCM(1, 426) = 426
GCD(1, 426) = ( 1 x 426 ) / 426
= 1 / 426
= 1
So, Greatest Common Divisor of 154, 787, 809, 426 is 1
