Given numbers are 172, 780, 566, 427
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(172, 780) = 33540
GCD(172, 780) = ( 172 x 780 ) / 33540
= 172 / 780
= 172
Step2:
LCM(4, 566) = 1132
GCD(4, 566) = ( 4 x 566 ) / 1132
= 4 / 566
= 4
Step3:
LCM(2, 427) = 854
GCD(2, 427) = ( 2 x 427 ) / 854
= 2 / 427
= 2
So, Greatest Common Divisor of 172, 780, 566, 427 is 1
