GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(722, 426) = 153786
GCD(722, 426) = ( 722 x 426 ) / 153786
= 722 / 426
= 722
Step2:
LCM(2, 771) = 1542
GCD(2, 771) = ( 2 x 771 ) / 1542
= 2 / 771
= 2
Step3:
LCM(1, 765) = 765
GCD(1, 765) = ( 1 x 765 ) / 765
= 1 / 765
= 1
So, Greatest Common Divisor of 722, 426, 771, 765 is 1
