GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(428, 985) = 421580
GCD(428, 985) = ( 428 x 985 ) / 421580
= 428 / 985
= 428
Step2:
LCM(1, 678) = 678
GCD(1, 678) = ( 1 x 678 ) / 678
= 1 / 678
= 1
Step3:
LCM(1, 611) = 611
GCD(1, 611) = ( 1 x 611 ) / 611
= 1 / 611
= 1
So, Greatest Common Divisor of 428, 985, 678, 611 is 1
