Given numbers are 140, 451, 821, 620
The list of prime factors of all numbers are
Prime factors of 140 are 2 x 2 x 5 x 7
Prime factors of 451 are 11 x 41
Prime factors of 821 are 821
Prime factors of 620 are 2 x 2 x 5 x 31
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 140, 451, 821, 620
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(140, 451) = 63140
GCD(140, 451) = ( 140 x 451 ) / 63140
= 140 / 451
= 140
Step2:
LCM(1, 821) = 821
GCD(1, 821) = ( 1 x 821 ) / 821
= 1 / 821
= 1
Step3:
LCM(1, 620) = 620
GCD(1, 620) = ( 1 x 620 ) / 620
= 1 / 620
= 1
So, Greatest Common Divisor of 140, 451, 821, 620 is 1
