GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(787, 974) = 766538
GCD(787, 974) = ( 787 x 974 ) / 766538
= 787 / 974
= 787
Step2:
LCM(1, 899) = 899
GCD(1, 899) = ( 1 x 899 ) / 899
= 1 / 899
= 1
Step3:
LCM(1, 821) = 821
GCD(1, 821) = ( 1 x 821 ) / 821
= 1 / 821
= 1
So, Greatest Common Divisor of 787, 974, 899, 821 is 1
