Given numbers are 380, 909, 547, 478
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(380, 909) = 345420
GCD(380, 909) = ( 380 x 909 ) / 345420
= 380 / 909
= 380
Step2:
LCM(1, 547) = 547
GCD(1, 547) = ( 1 x 547 ) / 547
= 1 / 547
= 1
Step3:
LCM(1, 478) = 478
GCD(1, 478) = ( 1 x 478 ) / 478
= 1 / 478
= 1
So, Greatest Common Divisor of 380, 909, 547, 478 is 1
