Given numbers are 172, 663, 136, 803
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(172, 663) = 114036
GCD(172, 663) = ( 172 x 663 ) / 114036
= 172 / 663
= 172
Step2:
LCM(1, 136) = 136
GCD(1, 136) = ( 1 x 136 ) / 136
= 1 / 136
= 1
Step3:
LCM(1, 803) = 803
GCD(1, 803) = ( 1 x 803 ) / 803
= 1 / 803
= 1
So, Greatest Common Divisor of 172, 663, 136, 803 is 1
