Given numbers are 638, 543, 485, 370
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(638, 543) = 346434
GCD(638, 543) = ( 638 x 543 ) / 346434
= 638 / 543
= 638
Step2:
LCM(1, 485) = 485
GCD(1, 485) = ( 1 x 485 ) / 485
= 1 / 485
= 1
Step3:
LCM(1, 370) = 370
GCD(1, 370) = ( 1 x 370 ) / 370
= 1 / 370
= 1
So, Greatest Common Divisor of 638, 543, 485, 370 is 1
