Given numbers are 391, 715, 710, 571
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(391, 715) = 279565
GCD(391, 715) = ( 391 x 715 ) / 279565
= 391 / 715
= 391
Step2:
LCM(1, 710) = 710
GCD(1, 710) = ( 1 x 710 ) / 710
= 1 / 710
= 1
Step3:
LCM(1, 571) = 571
GCD(1, 571) = ( 1 x 571 ) / 571
= 1 / 571
= 1
So, Greatest Common Divisor of 391, 715, 710, 571 is 1
