Given numbers are 685, 530, 74, 424
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(685, 530) = 72610
GCD(685, 530) = ( 685 x 530 ) / 72610
= 685 / 530
= 685
Step2:
LCM(5, 74) = 370
GCD(5, 74) = ( 5 x 74 ) / 370
= 5 / 74
= 5
Step3:
LCM(1, 424) = 424
GCD(1, 424) = ( 1 x 424 ) / 424
= 1 / 424
= 1
So, Greatest Common Divisor of 685, 530, 74, 424 is 1
