Given numbers are 659, 621, 166, 771
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(659, 621) = 409239
GCD(659, 621) = ( 659 x 621 ) / 409239
= 659 / 621
= 659
Step2:
LCM(1, 166) = 166
GCD(1, 166) = ( 1 x 166 ) / 166
= 1 / 166
= 1
Step3:
LCM(1, 771) = 771
GCD(1, 771) = ( 1 x 771 ) / 771
= 1 / 771
= 1
So, Greatest Common Divisor of 659, 621, 166, 771 is 1
