GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(687, 290) = 199230
GCD(687, 290) = ( 687 x 290 ) / 199230
= 687 / 290
= 687
Step2:
LCM(1, 532) = 532
GCD(1, 532) = ( 1 x 532 ) / 532
= 1 / 532
= 1
Step3:
LCM(1, 898) = 898
GCD(1, 898) = ( 1 x 898 ) / 898
= 1 / 898
= 1
So, Greatest Common Divisor of 687, 290, 532, 898 is 1
