Given numbers are 890, 656, 663, 392
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(890, 656) = 291920
GCD(890, 656) = ( 890 x 656 ) / 291920
= 890 / 656
= 890
Step2:
LCM(2, 663) = 1326
GCD(2, 663) = ( 2 x 663 ) / 1326
= 2 / 663
= 2
Step3:
LCM(1, 392) = 392
GCD(1, 392) = ( 1 x 392 ) / 392
= 1 / 392
= 1
So, Greatest Common Divisor of 890, 656, 663, 392 is 1
