Given numbers are 770, 669, 570, 275
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(770, 669) = 515130
GCD(770, 669) = ( 770 x 669 ) / 515130
= 770 / 669
= 770
Step2:
LCM(1, 570) = 570
GCD(1, 570) = ( 1 x 570 ) / 570
= 1 / 570
= 1
Step3:
LCM(1, 275) = 275
GCD(1, 275) = ( 1 x 275 ) / 275
= 1 / 275
= 1
So, Greatest Common Divisor of 770, 669, 570, 275 is 1
