Given numbers are 809, 755, 437, 661
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(809, 755) = 610795
GCD(809, 755) = ( 809 x 755 ) / 610795
= 809 / 755
= 809
Step2:
LCM(1, 437) = 437
GCD(1, 437) = ( 1 x 437 ) / 437
= 1 / 437
= 1
Step3:
LCM(1, 661) = 661
GCD(1, 661) = ( 1 x 661 ) / 661
= 1 / 661
= 1
So, Greatest Common Divisor of 809, 755, 437, 661 is 1
