Given numbers are 780, 348, 584, 765
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(780, 348) = 22620
GCD(780, 348) = ( 780 x 348 ) / 22620
= 780 / 348
= 780
Step2:
LCM(12, 584) = 1752
GCD(12, 584) = ( 12 x 584 ) / 1752
= 12 / 584
= 12
Step3:
LCM(4, 765) = 3060
GCD(4, 765) = ( 4 x 765 ) / 3060
= 4 / 765
= 4
So, Greatest Common Divisor of 780, 348, 584, 765 is 1
