Given numbers are 690, 729, 147, 349
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(690, 729) = 167670
GCD(690, 729) = ( 690 x 729 ) / 167670
= 690 / 729
= 690
Step2:
LCM(3, 147) = 147
GCD(3, 147) = ( 3 x 147 ) / 147
= 3 / 147
= 3
Step3:
LCM(3, 349) = 1047
GCD(3, 349) = ( 3 x 349 ) / 1047
= 3 / 349
= 3
So, Greatest Common Divisor of 690, 729, 147, 349 is 1
