Given numbers are 801, 969, 661, 556
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(801, 969) = 258723
GCD(801, 969) = ( 801 x 969 ) / 258723
= 801 / 969
= 801
Step2:
LCM(3, 661) = 1983
GCD(3, 661) = ( 3 x 661 ) / 1983
= 3 / 661
= 3
Step3:
LCM(1, 556) = 556
GCD(1, 556) = ( 1 x 556 ) / 556
= 1 / 556
= 1
So, Greatest Common Divisor of 801, 969, 661, 556 is 1
