Given numbers are 217, 602, 208, 781
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(217, 602) = 18662
GCD(217, 602) = ( 217 x 602 ) / 18662
= 217 / 602
= 217
Step2:
LCM(7, 208) = 1456
GCD(7, 208) = ( 7 x 208 ) / 1456
= 7 / 208
= 7
Step3:
LCM(1, 781) = 781
GCD(1, 781) = ( 1 x 781 ) / 781
= 1 / 781
= 1
So, Greatest Common Divisor of 217, 602, 208, 781 is 1
