Given numbers are 435, 669, 394, 670
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(435, 669) = 97005
GCD(435, 669) = ( 435 x 669 ) / 97005
= 435 / 669
= 435
Step2:
LCM(3, 394) = 1182
GCD(3, 394) = ( 3 x 394 ) / 1182
= 3 / 394
= 3
Step3:
LCM(1, 670) = 670
GCD(1, 670) = ( 1 x 670 ) / 670
= 1 / 670
= 1
So, Greatest Common Divisor of 435, 669, 394, 670 is 1
