Given numbers are 985, 565, 725, 387
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(985, 565) = 111305
GCD(985, 565) = ( 985 x 565 ) / 111305
= 985 / 565
= 985
Step2:
LCM(5, 725) = 725
GCD(5, 725) = ( 5 x 725 ) / 725
= 5 / 725
= 5
Step3:
LCM(5, 387) = 1935
GCD(5, 387) = ( 5 x 387 ) / 1935
= 5 / 387
= 5
So, Greatest Common Divisor of 985, 565, 725, 387 is 1
