Given numbers are 981, 612, 212, 523
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(981, 612) = 66708
GCD(981, 612) = ( 981 x 612 ) / 66708
= 981 / 612
= 981
Step2:
LCM(9, 212) = 1908
GCD(9, 212) = ( 9 x 212 ) / 1908
= 9 / 212
= 9
Step3:
LCM(1, 523) = 523
GCD(1, 523) = ( 1 x 523 ) / 523
= 1 / 523
= 1
So, Greatest Common Divisor of 981, 612, 212, 523 is 1
