Given numbers are 660, 758, 503, 991
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(660, 758) = 250140
GCD(660, 758) = ( 660 x 758 ) / 250140
= 660 / 758
= 660
Step2:
LCM(2, 503) = 1006
GCD(2, 503) = ( 2 x 503 ) / 1006
= 2 / 503
= 2
Step3:
LCM(1, 991) = 991
GCD(1, 991) = ( 1 x 991 ) / 991
= 1 / 991
= 1
So, Greatest Common Divisor of 660, 758, 503, 991 is 1
