Given numbers are 670, 381, 244, 129
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(670, 381) = 255270
GCD(670, 381) = ( 670 x 381 ) / 255270
= 670 / 381
= 670
Step2:
LCM(1, 244) = 244
GCD(1, 244) = ( 1 x 244 ) / 244
= 1 / 244
= 1
Step3:
LCM(1, 129) = 129
GCD(1, 129) = ( 1 x 129 ) / 129
= 1 / 129
= 1
So, Greatest Common Divisor of 670, 381, 244, 129 is 1
