Given numbers are 495, 668, 155, 620
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(495, 668) = 330660
GCD(495, 668) = ( 495 x 668 ) / 330660
= 495 / 668
= 495
Step2:
LCM(1, 155) = 155
GCD(1, 155) = ( 1 x 155 ) / 155
= 1 / 155
= 1
Step3:
LCM(1, 620) = 620
GCD(1, 620) = ( 1 x 620 ) / 620
= 1 / 620
= 1
So, Greatest Common Divisor of 495, 668, 155, 620 is 1
