Given numbers are 142, 135, 841, 661
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(142, 135) = 19170
GCD(142, 135) = ( 142 x 135 ) / 19170
= 142 / 135
= 142
Step2:
LCM(1, 841) = 841
GCD(1, 841) = ( 1 x 841 ) / 841
= 1 / 841
= 1
Step3:
LCM(1, 661) = 661
GCD(1, 661) = ( 1 x 661 ) / 661
= 1 / 661
= 1
So, Greatest Common Divisor of 142, 135, 841, 661 is 1
