GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(693, 819) = 9009
GCD(693, 819) = ( 693 x 819 ) / 9009
= 693 / 819
= 693
Step2:
LCM(63, 378) = 378
GCD(63, 378) = ( 63 x 378 ) / 378
= 63 / 378
= 63
Step3:
LCM(63, 340) = 21420
GCD(63, 340) = ( 63 x 340 ) / 21420
= 63 / 340
= 63
So, Greatest Common Divisor of 693, 819, 378, 340 is 1
