Given numbers are 221, 714, 485, 782
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(221, 714) = 9282
GCD(221, 714) = ( 221 x 714 ) / 9282
= 221 / 714
= 221
Step2:
LCM(17, 485) = 8245
GCD(17, 485) = ( 17 x 485 ) / 8245
= 17 / 485
= 17
Step3:
LCM(1, 782) = 782
GCD(1, 782) = ( 1 x 782 ) / 782
= 1 / 782
= 1
So, Greatest Common Divisor of 221, 714, 485, 782 is 1
