GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(428, 548) = 58636
GCD(428, 548) = ( 428 x 548 ) / 58636
= 428 / 548
= 428
Step2:
LCM(4, 909) = 3636
GCD(4, 909) = ( 4 x 909 ) / 3636
= 4 / 909
= 4
Step3:
LCM(1, 346) = 346
GCD(1, 346) = ( 1 x 346 ) / 346
= 1 / 346
= 1
So, Greatest Common Divisor of 428, 548, 909, 346 is 1
