Given numbers are 490, 770, 773, 406
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(490, 770) = 5390
GCD(490, 770) = ( 490 x 770 ) / 5390
= 490 / 770
= 490
Step2:
LCM(70, 773) = 54110
GCD(70, 773) = ( 70 x 773 ) / 54110
= 70 / 773
= 70
Step3:
LCM(1, 406) = 406
GCD(1, 406) = ( 1 x 406 ) / 406
= 1 / 406
= 1
So, Greatest Common Divisor of 490, 770, 773, 406 is 1
