Given numbers are 780, 734, 570, 254
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(780, 734) = 286260
GCD(780, 734) = ( 780 x 734 ) / 286260
= 780 / 734
= 780
Step2:
LCM(2, 570) = 570
GCD(2, 570) = ( 2 x 570 ) / 570
= 2 / 570
= 2
Step3:
LCM(2, 254) = 254
GCD(2, 254) = ( 2 x 254 ) / 254
= 2 / 254
= 2
So, Greatest Common Divisor of 780, 734, 570, 254 is 2
