Given numbers are 855, 156, 850, 440
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(855, 156) = 44460
GCD(855, 156) = ( 855 x 156 ) / 44460
= 855 / 156
= 855
Step2:
LCM(3, 850) = 2550
GCD(3, 850) = ( 3 x 850 ) / 2550
= 3 / 850
= 3
Step3:
LCM(1, 440) = 440
GCD(1, 440) = ( 1 x 440 ) / 440
= 1 / 440
= 1
So, Greatest Common Divisor of 855, 156, 850, 440 is 1
