Given numbers are 445, 535, 168, 770
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(445, 535) = 47615
GCD(445, 535) = ( 445 x 535 ) / 47615
= 445 / 535
= 445
Step2:
LCM(5, 168) = 840
GCD(5, 168) = ( 5 x 168 ) / 840
= 5 / 168
= 5
Step3:
LCM(1, 770) = 770
GCD(1, 770) = ( 1 x 770 ) / 770
= 1 / 770
= 1
So, Greatest Common Divisor of 445, 535, 168, 770 is 1
