Given numbers are 780, 165, 340, 904
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(780, 165) = 8580
GCD(780, 165) = ( 780 x 165 ) / 8580
= 780 / 165
= 780
Step2:
LCM(15, 340) = 1020
GCD(15, 340) = ( 15 x 340 ) / 1020
= 15 / 340
= 15
Step3:
LCM(5, 904) = 4520
GCD(5, 904) = ( 5 x 904 ) / 4520
= 5 / 904
= 5
So, Greatest Common Divisor of 780, 165, 340, 904 is 1
