Given numbers are 680, 314, 768, 221
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(680, 314) = 106760
GCD(680, 314) = ( 680 x 314 ) / 106760
= 680 / 314
= 680
Step2:
LCM(2, 768) = 768
GCD(2, 768) = ( 2 x 768 ) / 768
= 2 / 768
= 2
Step3:
LCM(2, 221) = 442
GCD(2, 221) = ( 2 x 221 ) / 442
= 2 / 221
= 2
So, Greatest Common Divisor of 680, 314, 768, 221 is 1
