Given numbers are 641, 670, 469, 689
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(641, 670) = 429470
GCD(641, 670) = ( 641 x 670 ) / 429470
= 641 / 670
= 641
Step2:
LCM(1, 469) = 469
GCD(1, 469) = ( 1 x 469 ) / 469
= 1 / 469
= 1
Step3:
LCM(1, 689) = 689
GCD(1, 689) = ( 1 x 689 ) / 689
= 1 / 689
= 1
So, Greatest Common Divisor of 641, 670, 469, 689 is 1
