Given numbers are 865, 655, 769, 437
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(865, 655) = 113315
GCD(865, 655) = ( 865 x 655 ) / 113315
= 865 / 655
= 865
Step2:
LCM(5, 769) = 3845
GCD(5, 769) = ( 5 x 769 ) / 3845
= 5 / 769
= 5
Step3:
LCM(1, 437) = 437
GCD(1, 437) = ( 1 x 437 ) / 437
= 1 / 437
= 1
So, Greatest Common Divisor of 865, 655, 769, 437 is 1
