Given numbers are 621, 751, 487, 447
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(621, 751) = 466371
GCD(621, 751) = ( 621 x 751 ) / 466371
= 621 / 751
= 621
Step2:
LCM(1, 487) = 487
GCD(1, 487) = ( 1 x 487 ) / 487
= 1 / 487
= 1
Step3:
LCM(1, 447) = 447
GCD(1, 447) = ( 1 x 447 ) / 447
= 1 / 447
= 1
So, Greatest Common Divisor of 621, 751, 487, 447 is 1
