Given numbers are 689, 205, 615, 887
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(689, 205) = 141245
GCD(689, 205) = ( 689 x 205 ) / 141245
= 689 / 205
= 689
Step2:
LCM(1, 615) = 615
GCD(1, 615) = ( 1 x 615 ) / 615
= 1 / 615
= 1
Step3:
LCM(1, 887) = 887
GCD(1, 887) = ( 1 x 887 ) / 887
= 1 / 887
= 1
So, Greatest Common Divisor of 689, 205, 615, 887 is 1
