Given numbers are 775, 415, 390, 253
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(775, 415) = 64325
GCD(775, 415) = ( 775 x 415 ) / 64325
= 775 / 415
= 775
Step2:
LCM(5, 390) = 390
GCD(5, 390) = ( 5 x 390 ) / 390
= 5 / 390
= 5
Step3:
LCM(5, 253) = 1265
GCD(5, 253) = ( 5 x 253 ) / 1265
= 5 / 253
= 5
So, Greatest Common Divisor of 775, 415, 390, 253 is 1
