Given numbers are 140, 254, 253, 487
The list of prime factors of all numbers are
Prime factors of 140 are 2 x 2 x 5 x 7
Prime factors of 254 are 2 x 127
Prime factors of 253 are 11 x 23
Prime factors of 487 are 487
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 140, 254, 253, 487
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(140, 254) = 17780
GCD(140, 254) = ( 140 x 254 ) / 17780
= 140 / 254
= 140
Step2:
LCM(2, 253) = 506
GCD(2, 253) = ( 2 x 253 ) / 506
= 2 / 253
= 2
Step3:
LCM(1, 487) = 487
GCD(1, 487) = ( 1 x 487 ) / 487
= 1 / 487
= 1
So, Greatest Common Divisor of 140, 254, 253, 487 is 1
