Given numbers are 720, 292, 161, 351
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(720, 292) = 52560
GCD(720, 292) = ( 720 x 292 ) / 52560
= 720 / 292
= 720
Step2:
LCM(4, 161) = 644
GCD(4, 161) = ( 4 x 161 ) / 644
= 4 / 161
= 4
Step3:
LCM(1, 351) = 351
GCD(1, 351) = ( 1 x 351 ) / 351
= 1 / 351
= 1
So, Greatest Common Divisor of 720, 292, 161, 351 is 1
