Given numbers are 423, 188, 193, 782
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(423, 188) = 1692
GCD(423, 188) = ( 423 x 188 ) / 1692
= 423 / 188
= 423
Step2:
LCM(47, 193) = 9071
GCD(47, 193) = ( 47 x 193 ) / 9071
= 47 / 193
= 47
Step3:
LCM(1, 782) = 782
GCD(1, 782) = ( 1 x 782 ) / 782
= 1 / 782
= 1
So, Greatest Common Divisor of 423, 188, 193, 782 is 1
