Given numbers are 690, 206, 207, 244
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(690, 206) = 71070
GCD(690, 206) = ( 690 x 206 ) / 71070
= 690 / 206
= 690
Step2:
LCM(2, 207) = 414
GCD(2, 207) = ( 2 x 207 ) / 414
= 2 / 207
= 2
Step3:
LCM(1, 244) = 244
GCD(1, 244) = ( 1 x 244 ) / 244
= 1 / 244
= 1
So, Greatest Common Divisor of 690, 206, 207, 244 is 1
