Given numbers are 677, 440, 545, 785
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(677, 440) = 297880
GCD(677, 440) = ( 677 x 440 ) / 297880
= 677 / 440
= 677
Step2:
LCM(1, 545) = 545
GCD(1, 545) = ( 1 x 545 ) / 545
= 1 / 545
= 1
Step3:
LCM(1, 785) = 785
GCD(1, 785) = ( 1 x 785 ) / 785
= 1 / 785
= 1
So, Greatest Common Divisor of 677, 440, 545, 785 is 1
