Given numbers are 771, 154, 877, 821
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(771, 154) = 118734
GCD(771, 154) = ( 771 x 154 ) / 118734
= 771 / 154
= 771
Step2:
LCM(1, 877) = 877
GCD(1, 877) = ( 1 x 877 ) / 877
= 1 / 877
= 1
Step3:
LCM(1, 821) = 821
GCD(1, 821) = ( 1 x 821 ) / 821
= 1 / 821
= 1
So, Greatest Common Divisor of 771, 154, 877, 821 is 1
