Given numbers are 785, 490, 201, 686
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(785, 490) = 76930
GCD(785, 490) = ( 785 x 490 ) / 76930
= 785 / 490
= 785
Step2:
LCM(5, 201) = 1005
GCD(5, 201) = ( 5 x 201 ) / 1005
= 5 / 201
= 5
Step3:
LCM(1, 686) = 686
GCD(1, 686) = ( 1 x 686 ) / 686
= 1 / 686
= 1
So, Greatest Common Divisor of 785, 490, 201, 686 is 1
