Given numbers are 170, 450, 539, 455
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(170, 450) = 7650
GCD(170, 450) = ( 170 x 450 ) / 7650
= 170 / 450
= 170
Step2:
LCM(10, 539) = 5390
GCD(10, 539) = ( 10 x 539 ) / 5390
= 10 / 539
= 10
Step3:
LCM(1, 455) = 455
GCD(1, 455) = ( 1 x 455 ) / 455
= 1 / 455
= 1
So, Greatest Common Divisor of 170, 450, 539, 455 is 1
