Given numbers are 823, 620, 507, 679
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(823, 620) = 510260
GCD(823, 620) = ( 823 x 620 ) / 510260
= 823 / 620
= 823
Step2:
LCM(1, 507) = 507
GCD(1, 507) = ( 1 x 507 ) / 507
= 1 / 507
= 1
Step3:
LCM(1, 679) = 679
GCD(1, 679) = ( 1 x 679 ) / 679
= 1 / 679
= 1
So, Greatest Common Divisor of 823, 620, 507, 679 is 1
