Given numbers are 712, 902, 717, 391
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(712, 902) = 321112
GCD(712, 902) = ( 712 x 902 ) / 321112
= 712 / 902
= 712
Step2:
LCM(2, 717) = 1434
GCD(2, 717) = ( 2 x 717 ) / 1434
= 2 / 717
= 2
Step3:
LCM(1, 391) = 391
GCD(1, 391) = ( 1 x 391 ) / 391
= 1 / 391
= 1
So, Greatest Common Divisor of 712, 902, 717, 391 is 1
