Given numbers are 688, 441, 493, 219
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(688, 441) = 303408
GCD(688, 441) = ( 688 x 441 ) / 303408
= 688 / 441
= 688
Step2:
LCM(1, 493) = 493
GCD(1, 493) = ( 1 x 493 ) / 493
= 1 / 493
= 1
Step3:
LCM(1, 219) = 219
GCD(1, 219) = ( 1 x 219 ) / 219
= 1 / 219
= 1
So, Greatest Common Divisor of 688, 441, 493, 219 is 1
