Given numbers are 213, 472, 673, 142
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(213, 472) = 100536
GCD(213, 472) = ( 213 x 472 ) / 100536
= 213 / 472
= 213
Step2:
LCM(1, 673) = 673
GCD(1, 673) = ( 1 x 673 ) / 673
= 1 / 673
= 1
Step3:
LCM(1, 142) = 142
GCD(1, 142) = ( 1 x 142 ) / 142
= 1 / 142
= 1
So, Greatest Common Divisor of 213, 472, 673, 142 is 1
