Given numbers are 660, 543, 253, 981
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(660, 543) = 119460
GCD(660, 543) = ( 660 x 543 ) / 119460
= 660 / 543
= 660
Step2:
LCM(3, 253) = 759
GCD(3, 253) = ( 3 x 253 ) / 759
= 3 / 253
= 3
Step3:
LCM(1, 981) = 981
GCD(1, 981) = ( 1 x 981 ) / 981
= 1 / 981
= 1
So, Greatest Common Divisor of 660, 543, 253, 981 is 1
