GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(494, 644) = 159068
GCD(494, 644) = ( 494 x 644 ) / 159068
= 494 / 644
= 494
Step2:
LCM(2, 243) = 486
GCD(2, 243) = ( 2 x 243 ) / 486
= 2 / 243
= 2
Step3:
LCM(1, 835) = 835
GCD(1, 835) = ( 1 x 835 ) / 835
= 1 / 835
= 1
So, Greatest Common Divisor of 494, 644, 243, 835 is 1
