Given numbers are 666, 886, 691, 620
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(666, 886) = 295038
GCD(666, 886) = ( 666 x 886 ) / 295038
= 666 / 886
= 666
Step2:
LCM(2, 691) = 1382
GCD(2, 691) = ( 2 x 691 ) / 1382
= 2 / 691
= 2
Step3:
LCM(1, 620) = 620
GCD(1, 620) = ( 1 x 620 ) / 620
= 1 / 620
= 1
So, Greatest Common Divisor of 666, 886, 691, 620 is 1
