Given numbers are 340, 548, 678, 391
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(340, 548) = 46580
GCD(340, 548) = ( 340 x 548 ) / 46580
= 340 / 548
= 340
Step2:
LCM(4, 678) = 1356
GCD(4, 678) = ( 4 x 678 ) / 1356
= 4 / 678
= 4
Step3:
LCM(2, 391) = 782
GCD(2, 391) = ( 2 x 391 ) / 782
= 2 / 391
= 2
So, Greatest Common Divisor of 340, 548, 678, 391 is 1
