GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(661, 971) = 641831
GCD(661, 971) = ( 661 x 971 ) / 641831
= 661 / 971
= 661
Step2:
LCM(1, 757) = 757
GCD(1, 757) = ( 1 x 757 ) / 757
= 1 / 757
= 1
Step3:
LCM(1, 443) = 443
GCD(1, 443) = ( 1 x 443 ) / 443
= 1 / 443
= 1
So, Greatest Common Divisor of 661, 971, 757, 443 is 1
