GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(825, 605) = 9075
GCD(825, 605) = ( 825 x 605 ) / 9075
= 825 / 605
= 825
Step2:
LCM(55, 987) = 54285
GCD(55, 987) = ( 55 x 987 ) / 54285
= 55 / 987
= 55
Step3:
LCM(1, 426) = 426
GCD(1, 426) = ( 1 x 426 ) / 426
= 1 / 426
= 1
So, Greatest Common Divisor of 825, 605, 987, 426 is 1
