GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(208, 684) = 35568
GCD(208, 684) = ( 208 x 684 ) / 35568
= 208 / 684
= 208
Step2:
LCM(4, 646) = 1292
GCD(4, 646) = ( 4 x 646 ) / 1292
= 4 / 646
= 4
Step3:
LCM(2, 943) = 1886
GCD(2, 943) = ( 2 x 943 ) / 1886
= 2 / 943
= 2
So, Greatest Common Divisor of 208, 684, 646, 943 is 1
