Given numbers are 421, 513, 778, 271
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(421, 513) = 215973
GCD(421, 513) = ( 421 x 513 ) / 215973
= 421 / 513
= 421
Step2:
LCM(1, 778) = 778
GCD(1, 778) = ( 1 x 778 ) / 778
= 1 / 778
= 1
Step3:
LCM(1, 271) = 271
GCD(1, 271) = ( 1 x 271 ) / 271
= 1 / 271
= 1
So, Greatest Common Divisor of 421, 513, 778, 271 is 1
