Given numbers are 656, 744, 827, 455
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(656, 744) = 61008
GCD(656, 744) = ( 656 x 744 ) / 61008
= 656 / 744
= 656
Step2:
LCM(8, 827) = 6616
GCD(8, 827) = ( 8 x 827 ) / 6616
= 8 / 827
= 8
Step3:
LCM(1, 455) = 455
GCD(1, 455) = ( 1 x 455 ) / 455
= 1 / 455
= 1
So, Greatest Common Divisor of 656, 744, 827, 455 is 1
