Given numbers are 658, 427, 193, 254
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(658, 427) = 40138
GCD(658, 427) = ( 658 x 427 ) / 40138
= 658 / 427
= 658
Step2:
LCM(7, 193) = 1351
GCD(7, 193) = ( 7 x 193 ) / 1351
= 7 / 193
= 7
Step3:
LCM(1, 254) = 254
GCD(1, 254) = ( 1 x 254 ) / 254
= 1 / 254
= 1
So, Greatest Common Divisor of 658, 427, 193, 254 is 1
