Given numbers are 660, 646, 919, 906
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(660, 646) = 213180
GCD(660, 646) = ( 660 x 646 ) / 213180
= 660 / 646
= 660
Step2:
LCM(2, 919) = 1838
GCD(2, 919) = ( 2 x 919 ) / 1838
= 2 / 919
= 2
Step3:
LCM(1, 906) = 906
GCD(1, 906) = ( 1 x 906 ) / 906
= 1 / 906
= 1
So, Greatest Common Divisor of 660, 646, 919, 906 is 1
