Given numbers are 685, 690, 276, 754
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(685, 690) = 94530
GCD(685, 690) = ( 685 x 690 ) / 94530
= 685 / 690
= 685
Step2:
LCM(5, 276) = 1380
GCD(5, 276) = ( 5 x 276 ) / 1380
= 5 / 276
= 5
Step3:
LCM(1, 754) = 754
GCD(1, 754) = ( 1 x 754 ) / 754
= 1 / 754
= 1
So, Greatest Common Divisor of 685, 690, 276, 754 is 1
