Given numbers are 210, 174, 263, 138
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(210, 174) = 6090
GCD(210, 174) = ( 210 x 174 ) / 6090
= 210 / 174
= 210
Step2:
LCM(6, 263) = 1578
GCD(6, 263) = ( 6 x 263 ) / 1578
= 6 / 263
= 6
Step3:
LCM(1, 138) = 138
GCD(1, 138) = ( 1 x 138 ) / 138
= 1 / 138
= 1
So, Greatest Common Divisor of 210, 174, 263, 138 is 1
