Given numbers are 655, 206, 423, 629
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(655, 206) = 134930
GCD(655, 206) = ( 655 x 206 ) / 134930
= 655 / 206
= 655
Step2:
LCM(1, 423) = 423
GCD(1, 423) = ( 1 x 423 ) / 423
= 1 / 423
= 1
Step3:
LCM(1, 629) = 629
GCD(1, 629) = ( 1 x 629 ) / 629
= 1 / 629
= 1
So, Greatest Common Divisor of 655, 206, 423, 629 is 1
