Given numbers are 370, 128, 138, 129
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(370, 128) = 23680
GCD(370, 128) = ( 370 x 128 ) / 23680
= 370 / 128
= 370
Step2:
LCM(2, 138) = 138
GCD(2, 138) = ( 2 x 138 ) / 138
= 2 / 138
= 2
Step3:
LCM(2, 129) = 258
GCD(2, 129) = ( 2 x 129 ) / 258
= 2 / 129
= 2
So, Greatest Common Divisor of 370, 128, 138, 129 is 1
