Given numbers are 172, 530, 243, 444
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(172, 530) = 45580
GCD(172, 530) = ( 172 x 530 ) / 45580
= 172 / 530
= 172
Step2:
LCM(2, 243) = 486
GCD(2, 243) = ( 2 x 243 ) / 486
= 2 / 243
= 2
Step3:
LCM(1, 444) = 444
GCD(1, 444) = ( 1 x 444 ) / 444
= 1 / 444
= 1
So, Greatest Common Divisor of 172, 530, 243, 444 is 1
