Given numbers are 690, 628, 436, 949
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(690, 628) = 216660
GCD(690, 628) = ( 690 x 628 ) / 216660
= 690 / 628
= 690
Step2:
LCM(2, 436) = 436
GCD(2, 436) = ( 2 x 436 ) / 436
= 2 / 436
= 2
Step3:
LCM(2, 949) = 1898
GCD(2, 949) = ( 2 x 949 ) / 1898
= 2 / 949
= 2
So, Greatest Common Divisor of 690, 628, 436, 949 is 1
