Given numbers are 666, 125, 661, 425
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(666, 125) = 83250
GCD(666, 125) = ( 666 x 125 ) / 83250
= 666 / 125
= 666
Step2:
LCM(1, 661) = 661
GCD(1, 661) = ( 1 x 661 ) / 661
= 1 / 661
= 1
Step3:
LCM(1, 425) = 425
GCD(1, 425) = ( 1 x 425 ) / 425
= 1 / 425
= 1
So, Greatest Common Divisor of 666, 125, 661, 425 is 1
