GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(660, 670) = 44220
GCD(660, 670) = ( 660 x 670 ) / 44220
= 660 / 670
= 660
Step2:
LCM(10, 838) = 4190
GCD(10, 838) = ( 10 x 838 ) / 4190
= 10 / 838
= 10
Step3:
LCM(2, 886) = 886
GCD(2, 886) = ( 2 x 886 ) / 886
= 2 / 886
= 2
So, Greatest Common Divisor of 660, 670, 838, 886 is 2
