Given numbers are 690, 215, 397, 529
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(690, 215) = 29670
GCD(690, 215) = ( 690 x 215 ) / 29670
= 690 / 215
= 690
Step2:
LCM(5, 397) = 1985
GCD(5, 397) = ( 5 x 397 ) / 1985
= 5 / 397
= 5
Step3:
LCM(1, 529) = 529
GCD(1, 529) = ( 1 x 529 ) / 529
= 1 / 529
= 1
So, Greatest Common Divisor of 690, 215, 397, 529 is 1
