GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(494, 208) = 3952
GCD(494, 208) = ( 494 x 208 ) / 3952
= 494 / 208
= 494
Step2:
LCM(26, 289) = 7514
GCD(26, 289) = ( 26 x 289 ) / 7514
= 26 / 289
= 26
Step3:
LCM(1, 830) = 830
GCD(1, 830) = ( 1 x 830 ) / 830
= 1 / 830
= 1
So, Greatest Common Divisor of 494, 208, 289, 830 is 1
