Given numbers are 621, 286, 566, 756
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(621, 286) = 177606
GCD(621, 286) = ( 621 x 286 ) / 177606
= 621 / 286
= 621
Step2:
LCM(1, 566) = 566
GCD(1, 566) = ( 1 x 566 ) / 566
= 1 / 566
= 1
Step3:
LCM(1, 756) = 756
GCD(1, 756) = ( 1 x 756 ) / 756
= 1 / 756
= 1
So, Greatest Common Divisor of 621, 286, 566, 756 is 1
