Given numbers are 688, 944, 798, 445
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(688, 944) = 40592
GCD(688, 944) = ( 688 x 944 ) / 40592
= 688 / 944
= 688
Step2:
LCM(16, 798) = 6384
GCD(16, 798) = ( 16 x 798 ) / 6384
= 16 / 798
= 16
Step3:
LCM(2, 445) = 890
GCD(2, 445) = ( 2 x 445 ) / 890
= 2 / 445
= 2
So, Greatest Common Divisor of 688, 944, 798, 445 is 1
