GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(897, 942) = 281658
GCD(897, 942) = ( 897 x 942 ) / 281658
= 897 / 942
= 897
Step2:
LCM(3, 457) = 1371
GCD(3, 457) = ( 3 x 457 ) / 1371
= 3 / 457
= 3
Step3:
LCM(1, 720) = 720
GCD(1, 720) = ( 1 x 720 ) / 720
= 1 / 720
= 1
So, Greatest Common Divisor of 897, 942, 457, 720 is 1
