GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(697, 787) = 548539
GCD(697, 787) = ( 697 x 787 ) / 548539
= 697 / 787
= 697
Step2:
LCM(1, 543) = 543
GCD(1, 543) = ( 1 x 543 ) / 543
= 1 / 543
= 1
Step3:
LCM(1, 189) = 189
GCD(1, 189) = ( 1 x 189 ) / 189
= 1 / 189
= 1
So, Greatest Common Divisor of 697, 787, 543, 189 is 1
