Given numbers are 487, 551, 751, 398
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(487, 551) = 268337
GCD(487, 551) = ( 487 x 551 ) / 268337
= 487 / 551
= 487
Step2:
LCM(1, 751) = 751
GCD(1, 751) = ( 1 x 751 ) / 751
= 1 / 751
= 1
Step3:
LCM(1, 398) = 398
GCD(1, 398) = ( 1 x 398 ) / 398
= 1 / 398
= 1
So, Greatest Common Divisor of 487, 551, 751, 398 is 1
