Prime factors of 545 are 5 x 109
Prime factors of 392 are 2 x 2 x 2 x 7 x 7
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 821, 134, 545, 392
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(821, 134) = 110014
GCD(821, 134) = ( 821 x 134 ) / 110014
= 821 / 134
= 821
Step2:
LCM(1, 545) = 545
GCD(1, 545) = ( 1 x 545 ) / 545
= 1 / 545
= 1
Step3:
LCM(1, 392) = 392
GCD(1, 392) = ( 1 x 392 ) / 392
= 1 / 392
= 1
So, Greatest Common Divisor of 821, 134, 545, 392 is 1
