GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(722, 285) = 10830
GCD(722, 285) = ( 722 x 285 ) / 10830
= 722 / 285
= 722
Step2:
LCM(19, 763) = 14497
GCD(19, 763) = ( 19 x 763 ) / 14497
= 19 / 763
= 19
Step3:
LCM(1, 688) = 688
GCD(1, 688) = ( 1 x 688 ) / 688
= 1 / 688
= 1
So, Greatest Common Divisor of 722, 285, 763, 688 is 1
