Given numbers are 840, 987, 785, 174
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(840, 987) = 39480
GCD(840, 987) = ( 840 x 987 ) / 39480
= 840 / 987
= 840
Step2:
LCM(21, 785) = 16485
GCD(21, 785) = ( 21 x 785 ) / 16485
= 21 / 785
= 21
Step3:
LCM(1, 174) = 174
GCD(1, 174) = ( 1 x 174 ) / 174
= 1 / 174
= 1
So, Greatest Common Divisor of 840, 987, 785, 174 is 1
