Given numbers are 657, 543, 531, 985
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(657, 543) = 118917
GCD(657, 543) = ( 657 x 543 ) / 118917
= 657 / 543
= 657
Step2:
LCM(3, 531) = 531
GCD(3, 531) = ( 3 x 531 ) / 531
= 3 / 531
= 3
Step3:
LCM(3, 985) = 2955
GCD(3, 985) = ( 3 x 985 ) / 2955
= 3 / 985
= 3
So, Greatest Common Divisor of 657, 543, 531, 985 is 1
