Given numbers are 170, 945, 129, 295
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(170, 945) = 32130
GCD(170, 945) = ( 170 x 945 ) / 32130
= 170 / 945
= 170
Step2:
LCM(5, 129) = 645
GCD(5, 129) = ( 5 x 129 ) / 645
= 5 / 129
= 5
Step3:
LCM(1, 295) = 295
GCD(1, 295) = ( 1 x 295 ) / 295
= 1 / 295
= 1
So, Greatest Common Divisor of 170, 945, 129, 295 is 1
