Given numbers are 687, 671, 653, 282
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(687, 671) = 460977
GCD(687, 671) = ( 687 x 671 ) / 460977
= 687 / 671
= 687
Step2:
LCM(1, 653) = 653
GCD(1, 653) = ( 1 x 653 ) / 653
= 1 / 653
= 1
Step3:
LCM(1, 282) = 282
GCD(1, 282) = ( 1 x 282 ) / 282
= 1 / 282
= 1
So, Greatest Common Divisor of 687, 671, 653, 282 is 1
