Given numbers are 694, 411, 490, 668
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(694, 411) = 285234
GCD(694, 411) = ( 694 x 411 ) / 285234
= 694 / 411
= 694
Step2:
LCM(1, 490) = 490
GCD(1, 490) = ( 1 x 490 ) / 490
= 1 / 490
= 1
Step3:
LCM(1, 668) = 668
GCD(1, 668) = ( 1 x 668 ) / 668
= 1 / 668
= 1
So, Greatest Common Divisor of 694, 411, 490, 668 is 1
