Given numbers are 690, 157, 713, 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, 157) = 108330
GCD(690, 157) = ( 690 x 157 ) / 108330
= 690 / 157
= 690
Step2:
LCM(1, 713) = 713
GCD(1, 713) = ( 1 x 713 ) / 713
= 1 / 713
= 1
Step3:
LCM(1, 349) = 349
GCD(1, 349) = ( 1 x 349 ) / 349
= 1 / 349
= 1
So, Greatest Common Divisor of 690, 157, 713, 349 is 1
