Given numbers are 140, 966, 855, 961
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(140, 966) = 9660
GCD(140, 966) = ( 140 x 966 ) / 9660
= 140 / 966
= 140
Step2:
LCM(14, 855) = 11970
GCD(14, 855) = ( 14 x 855 ) / 11970
= 14 / 855
= 14
Step3:
LCM(1, 961) = 961
GCD(1, 961) = ( 1 x 961 ) / 961
= 1 / 961
= 1
So, Greatest Common Divisor of 140, 966, 855, 961 is 1
