Given numbers are 385, 364, 157, 690
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(385, 364) = 20020
GCD(385, 364) = ( 385 x 364 ) / 20020
= 385 / 364
= 385
Step2:
LCM(7, 157) = 1099
GCD(7, 157) = ( 7 x 157 ) / 1099
= 7 / 157
= 7
Step3:
LCM(1, 690) = 690
GCD(1, 690) = ( 1 x 690 ) / 690
= 1 / 690
= 1
So, Greatest Common Divisor of 385, 364, 157, 690 is 1
