Given numbers are 391, 252, 964, 690
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(391, 252) = 98532
GCD(391, 252) = ( 391 x 252 ) / 98532
= 391 / 252
= 391
Step2:
LCM(1, 964) = 964
GCD(1, 964) = ( 1 x 964 ) / 964
= 1 / 964
= 1
Step3:
LCM(1, 690) = 690
GCD(1, 690) = ( 1 x 690 ) / 690
= 1 / 690
= 1
So, Greatest Common Divisor of 391, 252, 964, 690 is 1
