Given numbers are 860, 665, 680, 709
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(860, 665) = 114380
GCD(860, 665) = ( 860 x 665 ) / 114380
= 860 / 665
= 860
Step2:
LCM(5, 680) = 680
GCD(5, 680) = ( 5 x 680 ) / 680
= 5 / 680
= 5
Step3:
LCM(5, 709) = 3545
GCD(5, 709) = ( 5 x 709 ) / 3545
= 5 / 709
= 5
So, Greatest Common Divisor of 860, 665, 680, 709 is 1
