GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(208, 143) = 2288
GCD(208, 143) = ( 208 x 143 ) / 2288
= 208 / 143
= 208
Step2:
LCM(13, 961) = 12493
GCD(13, 961) = ( 13 x 961 ) / 12493
= 13 / 961
= 13
Step3:
LCM(1, 624) = 624
GCD(1, 624) = ( 1 x 624 ) / 624
= 1 / 624
= 1
So, Greatest Common Divisor of 208, 143, 961, 624 is 1
