Given numbers are 756, 669, 758, 249
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(756, 669) = 168588
GCD(756, 669) = ( 756 x 669 ) / 168588
= 756 / 669
= 756
Step2:
LCM(3, 758) = 2274
GCD(3, 758) = ( 3 x 758 ) / 2274
= 3 / 758
= 3
Step3:
LCM(1, 249) = 249
GCD(1, 249) = ( 1 x 249 ) / 249
= 1 / 249
= 1
So, Greatest Common Divisor of 756, 669, 758, 249 is 1
