Given numbers are 680, 221, 826, 426
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(680, 221) = 8840
GCD(680, 221) = ( 680 x 221 ) / 8840
= 680 / 221
= 680
Step2:
LCM(17, 826) = 14042
GCD(17, 826) = ( 17 x 826 ) / 14042
= 17 / 826
= 17
Step3:
LCM(1, 426) = 426
GCD(1, 426) = ( 1 x 426 ) / 426
= 1 / 426
= 1
So, Greatest Common Divisor of 680, 221, 826, 426 is 1
