Given numbers are 144, 400, 245, 869
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(144, 400) = 3600
GCD(144, 400) = ( 144 x 400 ) / 3600
= 144 / 400
= 144
Step2:
LCM(16, 245) = 3920
GCD(16, 245) = ( 16 x 245 ) / 3920
= 16 / 245
= 16
Step3:
LCM(1, 869) = 869
GCD(1, 869) = ( 1 x 869 ) / 869
= 1 / 869
= 1
So, Greatest Common Divisor of 144, 400, 245, 869 is 1
