Given numbers are 505, 745, 778, 839
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(505, 745) = 75245
GCD(505, 745) = ( 505 x 745 ) / 75245
= 505 / 745
= 505
Step2:
LCM(5, 778) = 3890
GCD(5, 778) = ( 5 x 778 ) / 3890
= 5 / 778
= 5
Step3:
LCM(1, 839) = 839
GCD(1, 839) = ( 1 x 839 ) / 839
= 1 / 839
= 1
So, Greatest Common Divisor of 505, 745, 778, 839 is 1
