Given numbers are 690, 897, 483, 257
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(690, 897) = 8970
GCD(690, 897) = ( 690 x 897 ) / 8970
= 690 / 897
= 690
Step2:
LCM(69, 483) = 483
GCD(69, 483) = ( 69 x 483 ) / 483
= 69 / 483
= 69
Step3:
LCM(69, 257) = 17733
GCD(69, 257) = ( 69 x 257 ) / 17733
= 69 / 257
= 69
So, Greatest Common Divisor of 690, 897, 483, 257 is 1
