Given numbers are 481, 780, 345, 436
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(481, 780) = 28860
GCD(481, 780) = ( 481 x 780 ) / 28860
= 481 / 780
= 481
Step2:
LCM(13, 345) = 4485
GCD(13, 345) = ( 13 x 345 ) / 4485
= 13 / 345
= 13
Step3:
LCM(1, 436) = 436
GCD(1, 436) = ( 1 x 436 ) / 436
= 1 / 436
= 1
So, Greatest Common Divisor of 481, 780, 345, 436 is 1
