Given numbers are 713, 688, 803, 391
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(713, 688) = 490544
GCD(713, 688) = ( 713 x 688 ) / 490544
= 713 / 688
= 713
Step2:
LCM(1, 803) = 803
GCD(1, 803) = ( 1 x 803 ) / 803
= 1 / 803
= 1
Step3:
LCM(1, 391) = 391
GCD(1, 391) = ( 1 x 391 ) / 391
= 1 / 391
= 1
So, Greatest Common Divisor of 713, 688, 803, 391 is 1
