Given numbers are 668, 305, 377, 402
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(668, 305) = 203740
GCD(668, 305) = ( 668 x 305 ) / 203740
= 668 / 305
= 668
Step2:
LCM(1, 377) = 377
GCD(1, 377) = ( 1 x 377 ) / 377
= 1 / 377
= 1
Step3:
LCM(1, 402) = 402
GCD(1, 402) = ( 1 x 402 ) / 402
= 1 / 402
= 1
So, Greatest Common Divisor of 668, 305, 377, 402 is 1
