Given numbers are 138, 661, 342, 528
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(138, 661) = 91218
GCD(138, 661) = ( 138 x 661 ) / 91218
= 138 / 661
= 138
Step2:
LCM(1, 342) = 342
GCD(1, 342) = ( 1 x 342 ) / 342
= 1 / 342
= 1
Step3:
LCM(1, 528) = 528
GCD(1, 528) = ( 1 x 528 ) / 528
= 1 / 528
= 1
So, Greatest Common Divisor of 138, 661, 342, 528 is 1
