Given numbers are 709, 613, 205, 688
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(709, 613) = 434617
GCD(709, 613) = ( 709 x 613 ) / 434617
= 709 / 613
= 709
Step2:
LCM(1, 205) = 205
GCD(1, 205) = ( 1 x 205 ) / 205
= 1 / 205
= 1
Step3:
LCM(1, 688) = 688
GCD(1, 688) = ( 1 x 688 ) / 688
= 1 / 688
= 1
So, Greatest Common Divisor of 709, 613, 205, 688 is 1
