Given numbers are 897, 711, 665, 687
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(897, 711) = 212589
GCD(897, 711) = ( 897 x 711 ) / 212589
= 897 / 711
= 897
Step2:
LCM(3, 665) = 1995
GCD(3, 665) = ( 3 x 665 ) / 1995
= 3 / 665
= 3
Step3:
LCM(1, 687) = 687
GCD(1, 687) = ( 1 x 687 ) / 687
= 1 / 687
= 1
So, Greatest Common Divisor of 897, 711, 665, 687 is 1
