Given numbers are 820, 521, 496, 770
The list of prime factors of all numbers are
Prime factors of 820 are 2 x 2 x 5 x 41
Prime factors of 521 are 521
Prime factors of 496 are 2 x 2 x 2 x 2 x 31
Prime factors of 770 are 2 x 5 x 7 x 11
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 820, 521, 496, 770
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(820, 521) = 427220
GCD(820, 521) = ( 820 x 521 ) / 427220
= 820 / 521
= 820
Step2:
LCM(1, 496) = 496
GCD(1, 496) = ( 1 x 496 ) / 496
= 1 / 496
= 1
Step3:
LCM(1, 770) = 770
GCD(1, 770) = ( 1 x 770 ) / 770
= 1 / 770
= 1
So, Greatest Common Divisor of 820, 521, 496, 770 is 1
