Given numbers are 981, 213, 625, 746
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(981, 213) = 69651
GCD(981, 213) = ( 981 x 213 ) / 69651
= 981 / 213
= 981
Step2:
LCM(3, 625) = 1875
GCD(3, 625) = ( 3 x 625 ) / 1875
= 3 / 625
= 3
Step3:
LCM(1, 746) = 746
GCD(1, 746) = ( 1 x 746 ) / 746
= 1 / 746
= 1
So, Greatest Common Divisor of 981, 213, 625, 746 is 1
