Given numbers are 245, 380, 797, 745
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(245, 380) = 18620
GCD(245, 380) = ( 245 x 380 ) / 18620
= 245 / 380
= 245
Step2:
LCM(5, 797) = 3985
GCD(5, 797) = ( 5 x 797 ) / 3985
= 5 / 797
= 5
Step3:
LCM(1, 745) = 745
GCD(1, 745) = ( 1 x 745 ) / 745
= 1 / 745
= 1
So, Greatest Common Divisor of 245, 380, 797, 745 is 1
