GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(398, 772) = 153628
GCD(398, 772) = ( 398 x 772 ) / 153628
= 398 / 772
= 398
Step2:
LCM(2, 690) = 690
GCD(2, 690) = ( 2 x 690 ) / 690
= 2 / 690
= 2
Step3:
LCM(2, 739) = 1478
GCD(2, 739) = ( 2 x 739 ) / 1478
= 2 / 739
= 2
So, Greatest Common Divisor of 398, 772, 690, 739 is 1
