Given numbers are 915, 162, 661, 804
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(915, 162) = 49410
GCD(915, 162) = ( 915 x 162 ) / 49410
= 915 / 162
= 915
Step2:
LCM(3, 661) = 1983
GCD(3, 661) = ( 3 x 661 ) / 1983
= 3 / 661
= 3
Step3:
LCM(1, 804) = 804
GCD(1, 804) = ( 1 x 804 ) / 804
= 1 / 804
= 1
So, Greatest Common Divisor of 915, 162, 661, 804 is 1
