GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(169, 840) = 141960
GCD(169, 840) = ( 169 x 840 ) / 141960
= 169 / 840
= 169
Step2:
LCM(1, 486) = 486
GCD(1, 486) = ( 1 x 486 ) / 486
= 1 / 486
= 1
Step3:
LCM(1, 219) = 219
GCD(1, 219) = ( 1 x 219 ) / 219
= 1 / 219
= 1
So, Greatest Common Divisor of 169, 840, 486, 219 is 1
