Given numbers are 920, 657, 890, 988
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(920, 657) = 604440
GCD(920, 657) = ( 920 x 657 ) / 604440
= 920 / 657
= 920
Step2:
LCM(1, 890) = 890
GCD(1, 890) = ( 1 x 890 ) / 890
= 1 / 890
= 1
Step3:
LCM(1, 988) = 988
GCD(1, 988) = ( 1 x 988 ) / 988
= 1 / 988
= 1
So, Greatest Common Divisor of 920, 657, 890, 988 is 1
