Given numbers are 880, 420, 696, 771
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(880, 420) = 18480
GCD(880, 420) = ( 880 x 420 ) / 18480
= 880 / 420
= 880
Step2:
LCM(20, 696) = 3480
GCD(20, 696) = ( 20 x 696 ) / 3480
= 20 / 696
= 20
Step3:
LCM(4, 771) = 3084
GCD(4, 771) = ( 4 x 771 ) / 3084
= 4 / 771
= 4
So, Greatest Common Divisor of 880, 420, 696, 771 is 1
