Given numbers are 660, 558, 940, 441
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(660, 558) = 61380
GCD(660, 558) = ( 660 x 558 ) / 61380
= 660 / 558
= 660
Step2:
LCM(6, 940) = 2820
GCD(6, 940) = ( 6 x 940 ) / 2820
= 6 / 940
= 6
Step3:
LCM(2, 441) = 882
GCD(2, 441) = ( 2 x 441 ) / 882
= 2 / 441
= 2
So, Greatest Common Divisor of 660, 558, 940, 441 is 1
