GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(133, 981) = 130473
GCD(133, 981) = ( 133 x 981 ) / 130473
= 133 / 981
= 133
Step2:
LCM(1, 783) = 783
GCD(1, 783) = ( 1 x 783 ) / 783
= 1 / 783
= 1
Step3:
LCM(1, 621) = 621
GCD(1, 621) = ( 1 x 621 ) / 621
= 1 / 621
= 1
So, Greatest Common Divisor of 133, 981, 783, 621 is 1
