Given numbers are 425, 247, 621, 803
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(425, 247) = 104975
GCD(425, 247) = ( 425 x 247 ) / 104975
= 425 / 247
= 425
Step2:
LCM(1, 621) = 621
GCD(1, 621) = ( 1 x 621 ) / 621
= 1 / 621
= 1
Step3:
LCM(1, 803) = 803
GCD(1, 803) = ( 1 x 803 ) / 803
= 1 / 803
= 1
So, Greatest Common Divisor of 425, 247, 621, 803 is 1
