Given numbers are 897, 115, 694, 140
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(897, 115) = 4485
GCD(897, 115) = ( 897 x 115 ) / 4485
= 897 / 115
= 897
Step2:
LCM(23, 694) = 15962
GCD(23, 694) = ( 23 x 694 ) / 15962
= 23 / 694
= 23
Step3:
LCM(1, 140) = 140
GCD(1, 140) = ( 1 x 140 ) / 140
= 1 / 140
= 1
So, Greatest Common Divisor of 897, 115, 694, 140 is 1
