Given numbers are 608, 988, 445, 661
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(608, 988) = 7904
GCD(608, 988) = ( 608 x 988 ) / 7904
= 608 / 988
= 608
Step2:
LCM(76, 445) = 33820
GCD(76, 445) = ( 76 x 445 ) / 33820
= 76 / 445
= 76
Step3:
LCM(1, 661) = 661
GCD(1, 661) = ( 1 x 661 ) / 661
= 1 / 661
= 1
So, Greatest Common Divisor of 608, 988, 445, 661 is 1
