Given numbers are 485, 740, 247, 381
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(485, 740) = 71780
GCD(485, 740) = ( 485 x 740 ) / 71780
= 485 / 740
= 485
Step2:
LCM(5, 247) = 1235
GCD(5, 247) = ( 5 x 247 ) / 1235
= 5 / 247
= 5
Step3:
LCM(1, 381) = 381
GCD(1, 381) = ( 1 x 381 ) / 381
= 1 / 381
= 1
So, Greatest Common Divisor of 485, 740, 247, 381 is 1
