Given numbers are 710, 278, 680, 805
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(710, 278) = 98690
GCD(710, 278) = ( 710 x 278 ) / 98690
= 710 / 278
= 710
Step2:
LCM(2, 680) = 680
GCD(2, 680) = ( 2 x 680 ) / 680
= 2 / 680
= 2
Step3:
LCM(2, 805) = 1610
GCD(2, 805) = ( 2 x 805 ) / 1610
= 2 / 805
= 2
So, Greatest Common Divisor of 710, 278, 680, 805 is 1
