Given numbers are 170, 723, 535, 438
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(170, 723) = 122910
GCD(170, 723) = ( 170 x 723 ) / 122910
= 170 / 723
= 170
Step2:
LCM(1, 535) = 535
GCD(1, 535) = ( 1 x 535 ) / 535
= 1 / 535
= 1
Step3:
LCM(1, 438) = 438
GCD(1, 438) = ( 1 x 438 ) / 438
= 1 / 438
= 1
So, Greatest Common Divisor of 170, 723, 535, 438 is 1
