Given numbers are 753, 172, 423, 813
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(753, 172) = 129516
GCD(753, 172) = ( 753 x 172 ) / 129516
= 753 / 172
= 753
Step2:
LCM(1, 423) = 423
GCD(1, 423) = ( 1 x 423 ) / 423
= 1 / 423
= 1
Step3:
LCM(1, 813) = 813
GCD(1, 813) = ( 1 x 813 ) / 813
= 1 / 813
= 1
So, Greatest Common Divisor of 753, 172, 423, 813 is 1
